Surface Plasmon Images



The goal of this endeavour is to get a "feel" for the parameters of how plasmons couple with molecules. Just as in learning any new form of spectroscopy, this is probably best done with a little theory and a lot of real examples. Right now we have the following list of topics:

General Introduction to Plasmons (Steffen Jockusch)
ATR setup for the excitation of surface plasmons (PSPs) in Kretschmann geometry: (left) a thin metal film (thickness ~50 nm) is evaporated onto the base of a glass prism and acts as a resonator driven by the photon field; (right) the resonant excitation of the PSP wave is seen in the reflectivity curve as a sharp dip at coupling angle theta0. (Biosensors & Bioelectronics 1995, 10, 903-916)
Origin of surface plasmon resonance due to coherent interaction of the electrons in the conduction band with light. (Chem. Soc. Rev. 2006, 35, 209-217)

Surface Enhanced IR [SEIR] (Ben Dach)
A schematic representation of the electromagnetic (EM) mechanism of Surface Enhanced Infrared Absorption (SEIRA) on metal island films. The metal islands are polarized by the incident infrared photon field through the excitation of collective electron resonance, or localized plasmon, modes, and the dipole p induced in an island generates a local EM field stronger than the incident infrared photon field around the island. (Topics Appl. Phys. 201, 81, 163-187.) AFM images of 5-, and 10-nm Pd island films deposited on surface-oxidized Si (100). These surfaces were shown to exhibit substantial enhancement of infrared absorption by C60. (Isr. J. Chem. 2006, 46, 257-263.)

Surface Enhanced Raman [SERS] (Cheng Guo)

Surface Enhanced Fluorescence [SEFS] (Ellane Park)
Calculated intensities and emission spectra for Rh6G in a silver shell. (Proc. SPIE 2006, 6099, 609909) Fluorescence rate as a function of gold particle-fluorophore distance z for a vertically oriented molecule. Inset is a scheme of the experiment. (a) COmparison experiment-model for an embedded molecule; the solid curve is the MMP simulation; the dots are for the experiment performed with a d = 80 nm gold sphere on a single nile blue molecule. (b) Calculated fluorescence rate of a free fluorophore normalized to the free space value for different particles of diamete d. The solid curves correspond to the dipole approximation which fails for short distance. (J. Phys. D: Appl. Phys. 2008, 41, 1-31)
 
Fluorescence enhancement above a nanoparticle. (a) Fluorescence decay curves of Rhodamine 6G in open solution and into a d = 150 nm nanohole. (b) Three-dimensional finite-element time-domain simulation of the intensity distribution for a d = 50 nm nanohole on a silica substrate in solution. (J. Phys. D: Appl. Phys. 2008, 41, 1-31)  

Surface Enhanced Sum Harmonic Generation [SESHG] and Sum Frequency Generation [SESFG] (Yi Rao)
AFM and SEM micrograph of platinum nanoparticle array. Particles are 40 nm diameter spaced 150 nm between particles. (J. Chem. Phys. 2000, 113, 5432-5438.) SFG spectra of CO adsorbed on (a) 40 nm Pt nanoparticle arrays, (b) 200 nm Pt nanoparticle arrays, (c) smooth Pt film. SSP polarization shown. (J. Chem. Phys. 2000, 113, 5432-5438.)
