Laser Induced Luminescence Spectroscopy on Solid Substrates: An Overview

This paper provides an overview of the photophysical processes and analytical applications of high-resolution luminescence spectroscopy using solid samples. Experimental results are discussed within the framework of a theoretical model involving isolated guest molecules weakly interacting with the host solid substrate. Examples are given to illustrate the spectral structure of luminescence spectra exhibiting zero-phonon lines and phonon wings. Effects of experimental parameters such as temperature are discussed. Analytical considerations on the various laser-based techniques in fluorescence and phosphorescence analysis are reviewed and discussed in detail.
