Abstract
Some photo-physical parameters of 1 x 10(-4) and 5.9 x 10(-4) M samples of rhodamine 6G in a 2-hydroxyethyl-methacrylate methyl-methacrylate copolymer (volume mixture 1:1) are determined and compared with rhodamine 6G in meth anol. They include the absorption cross-section and stimulated emission cro ss-section spectra, the fluorescence quantum distributions, quantum yields and lifetimes. The photo-degradation under steady-state and pulsed excitati on is investigated. The saturable absorption behaviour under picosecond las er excitation is studied. (C) 2000 Elsevier Science B.V.
