Abstract

The dissolution characteristics of thin polymethyl methacrylate films, studied by simultaneous laser interferometry and fluorescence quenching (LIFQ) experiments, are reported. These require UV- transparent substrates. The influence of the substrate material on the LIFQ results was investigated. The results obtained with sapphire substrates allowed us to calculate the thickness of the solvent-swollen gel layer at the beginning and at the end of the dissolution process. © 1992 Optical Society of America.
