The application of photoacoustic technique was demonstrated for measuring the thermal diffusivity of R6G doped in solid matrix poly (methylrnethacrylate) (PMMA) and copolymer of methyl methacrylate(MMA) with 2-hydroxyethyl methacrylate(HEMA) [P(MMA:HEMA)]. The thermal diffusivity value obtained for...
