Abstract

Attenuated total reflection and photoacoustic measurements have been employed to study the decay channels of plasmon surface polaritons optically excited at the Ag-air interface. We show that it is possible to analyse the radiative and non-radiative decay quantitatively by comparing measurements taken with transparent and blackened cavities, respectively. In the first case only light that is thermalized by radiationless processes in the Ag film produces a photoacoustic signal. In the blackened cell, however, light that is either transmitted through the Ag film or reemitted by the radiative decay of excited polaritons also contributes to the photoacoustic intensity.

Otherwise, the photoacoustic effect is substantially the same, except that a non-propagating evanescent field is exciting the acoustic waves rather than propagating photons through a medium. Many groups have developed applications [8–10,19,22–27,32,33,38–40] and variations [39,41–57] on the fundamental TIRPAS technique since the early 1980s. Some of these methods even employed surface plasmon resonance to enhance the photoacoustic effect compared to TIRPAS.
Thin films continue to show great promise for improving devices in optical applications, such as improved chemical sensors based on surface plasmon resonance devices (Gardon et al. (2008) [1] and Brolo et al. (2004) [2]). While ellipsometry and reflectometry are standard characterization techniques for determining thickness and refractive index of thin films, these techniques tend to require highly reflective or polished films and rely on empirical equations like the Cauchy, Briot, Hartmann, Conrady, and Sellmeier empirical dispersion equations. While these empirical equations may be accurate in some wavelength ranges and for non-conductive materials, the researcher must identify which equation is appropriate for the film being tested and wavelength range desired. To improve ease of testing, we have created a new technique, Optical Tunneling Photoacoustic Spectroscopy (OTPAS), that uses light-induced ultrasound to measure the amount of optical tunneling that has occurred with frustrated total internal reflection through a thin film. The OTPAS system allows a researcher to obtain thickness and refractive index estimates of transparent films without polishing or knowledge of empirical equations prior to the experiment. Scans of 200 nm thick MgF₂ films were used to compare ellipsometry with the OTPAS technique. An example of our results shows mean refractive index and thickness estimates of 1.395±0.011 and 220±19 nm versus 1.392±0.002 and 195.2±1.8 nm at 532 nm for ellipsometry, which suggests a general agreement between the two techniques. We present OTPAS to be used for the determination of optical properties of transparent single layer films in cases where empirical equations cannot be used or in cases of low optical reflection.
High-resolution microscopy of plasmon field distributions by scanning tunneling luminescence and photoemission electron microscopies
2012, Comptes Rendus Physique
The exploitation of plasmon resonances to promote the interaction between conjugated molecules and optical fields motivates intensive research. The objectives are to understand the mechanisms of plasmon-mediated interactions, and to realize molecularly- or atomically-precise metal nanostructures, combining field enhancements and optical antenna effects. In this review paper, we present examples of plasmonic-field mappings based on scanning tunneling microscope (STM)-induced light emission or multiphoton photoemission (PEEM), two techniques among those which offer todayʼs best spatial resolutions for plasmon microscopy. An unfamiliar property of the junction of an STM is its ability to behave as a highly localized source of light. It can be exploited to probe optoelectronic properties, in particular plasmonic fields, with ultimate subnanometer spatial resolution, an advantage balanced by a sometimes delicate deconvolution of local-probe influence. Alternatively, local-probe disadvantages can be overcome by imaging the photoemitted electrons, using well-established electron optics. This allows obtaining two-dimensional intensity maps reflecting the unperturbed distribution of the optical near field. This approach provides full field spectroscopic images with a routine spatial resolution of the order of 20 nm (down to 5 nm with recent aberration corrected instruments).
Lʼexploitation des résonances plasmons dans le but de promouvoir lʼinteraction entre des molécules conjuguées et des champs optiques motive actuellement dʼintenses recherches. Les objectifs en sont la compréhension du rôle médiateur des interactions optiques joué par les modes de plasmon et la réalisation de nanostructures métalliques avec une précision moléculaire voire atomique, combinant les effets dʼexaltation de champ et dʼantennes optiques. Dans cet article de synthèse, nous présentons des exemples de cartographie des champs plasmoniques basés sur deux techniques de microscopie : lʼémission de lumière induite par microscopie tunnel à balayage de sonde (scanning tunneling microscopy — STM) et lʼimagerie de photoémission multiphotonique (photoemission electron microscopy — PEEM), deux techniques parmi celles qui offrent aujourdʼhui les meilleures résolutions spatiales pour la microscopie plasmonique. Une propriété peu conventionnelle de la jonction du microscope à effet tunnel est sa capacité à se comporter comme une source localisée de lumière. Celle-ci peut être exploitée pour sonder localement les propriétés opto-électroniques en surface, en particulier les modes plasmoniques, avec une résolution spatiale inférieure au nanomètre. Lʼavantage de cette résolution ultime est cependant contrebalancé par la nécessité dʼune déconvolution parfois délicate de lʼinfluence de la sonde. Alternativement, les inconvénients inhérents aux techniques de sondes locales peuvent être surmontés par lʼimagerie des électrons photoémis, en utilisant les méthodes bien établies dʼoptique électronique. Ceci permet lʼobtention de cartes dʼintensité en deux dimensions reflétant directement la distribution non perturbée du champ proche optique. Cette approche fournit des images avec une résolution spatiale de lʼordre de 20 nm en routine et pouvant atteindre 5 nm avec les instruments les plus récents, incluant un dispositif de correction des aberrations.
Surface plasmon resonance (SPR) reflectance imaging: Far-field recognition of near-field phenomena
2012, Optics and Lasers in Engineering

On the other hand, the dip curve becomes wider when wavelengths become shorter. It can be said that the wider curve is caused by the increased damping for the SPR propagation along the interface with a decreasing wavelength [35,69–73]. Thus, the sharper dip implies less damping of SPPs, meaning that SPPs excited at one place can travel further along the metal surface and leave longer trails, possibly deteriorating the spatial image resolution [74,75].
The surface plasmon resonance (SPR) reflectance imaging technique provides a label-free visualization tool to characterize the near-field fluidic transport properties within 100 nm from the solid surface. The key idea is that the SPR reflectance intensity varies with the near-field refractive index (RI) of the test fluid, which in turn depends on the micro- and nano-fluidic scalar properties such as concentrations, temperatures, and phase changes, occurring in the near-field. As essential knowledge to understand and implement the SPR reflectance imaging technique, this paper presents discussions on the basics of surface plasmon polaritons (SPPs), surface plasmon resonance (SPR), setup of the SPR reflectance imaging system, and the SPR reflectance imaging resolution. The second part of the paper elaborates the applications of the SPR imaging sensor technique in characterizing the near-field fingerprints of nanofluidic evaporative self-assembly.
Laser-induced thermal effect in surface plasmon resonance
2010, Analytica Chimica Acta

The thermal effect from the irradiation of laser beam, which is typically of weak power (≤5 mW), has been commonly ignored. The thermo-optical effect (transformation of the light energy into heat) in SPR, including the heat conversion process, the conversion efficiency, and thermal distribution, has been researched for many years [27–30]. In SPR, due to the resonance, a certain fraction of the surface plasmon energy is converted into heat through nonradiative relaxation (evanescent wave) [31].
In this work, thermal effect inherent in long-term irradiation of a focused laser beam may become a major source of error in surface plasmon resonance (SPR) measurements, especially when infinitesimal signals (e.g., reorganization of monolayers or conformational changes of immobilized proteins) are measured. The laser-induced thermal effect was examined by continuously monitoring changes brought about by injecting 2% ethanol solution into a flow cell housing bare and chemically modified gold films that had been irradiated by a laser beam for various times, and a maximum relative error of 21% was obtained. Factors affecting the SPR response, namely solution flow rate, compactness of the adsorbate layer, and power of the laser beam, were examined. The SPR dip shift (SPR angular shift) was shown to be dependent not only on the magnitude of the laser power but also on the thermal dissipation at the metal–solution interface. With a better understanding of the parameters affecting the thermal energy dissipation and the temperature dependence of the SPR signals, measures can be taken to improve the accuracy of SPR data. We show as an example that, if the laser-induced thermal effect is not considered or reduced, accuracy in determinating redox-triggered reorganization of a pre-immobilized 11-ferrocenylundecanethiol self-assembled monolayer (SAM) may be decreased by more than 40%, leading to an erroneous conclusion.
A new sensor for the thermo-optical detection of surface plasmon resonance
2007, Sensors and Actuators, A: Physical
A new sensor for the thermo-optical detection of surface plasmon resonance (SPR) is presented. The sensor incorporates a grating coupler, patterned in a thin noble metal film (Au or Ag, respectively) for excitation of SPR by monochromatic laser light and a thin film thermal sensor for detection of the temperature change by absorbed radiation power. High sensitivity of the sensor is obtained by micromechanical patterning of a thin membrane area below the sensitive metal film. Design optimization has been performed by FEM simulations. First results regarding the thermal detection of SPR during the formation of supramolecular architectures on a silver film are presented. The measurements are compared with the results, obtained with conventional optical sensor devices.
Microscopic fundamentals of electromagnetic functional metal/dielectric nanocomposite multilayer films
2000, Surface and Coatings Technology
To understand the physical mechanism of electromagnetic response and potential energy conversion mode in nanostructured materials, especially in metal/dielectric nanocomposite multilayers, a theoretical framework has been suggested. It involves the prerequisite of response, transmission effect, mode of response, plasma model, efficiency of response mode, and size effect of constitutive characteristics. Experimental results have proved that the size effect exists for electrical conductivity, optical constants, permittivity, permeability and carrier density in ultrathin Al, Ti and Fe films as the thickness of the film decreases to a nanometer size range. Principles for designing nanostructures are discussed.
