Title: Photosensitivity of Laser Dye Mixtures in Polymer Matrix – A Photoacoustic Study
Author: Annieta, Philip K; Lyjo, K Joseph; Litty, Irimpan; Radhakrishnan, P; Nampoori, V P N
Abstract: Laser induced photoacoustic (PA) technique is used in the study of photostability of polymethyl methacrylate (PMMA) films doped with Rhodamine 6G -Rhodamine B dye system. Energy transfer from a donor molecule to an acceptor molecule in a dye mixture affects the output of the dye system. Details of investigations on the role of laser power, modulation frequency and the irradiation wavelength on the photosensitivity of the dye mixture doped PMMA films are presented.
