Abstract
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 R6G-doped PMMA is higher than the copolymer ofR6G-doped [P(MMA:HEMA)]. The optical spectra of the samples were measured by using a fibre optics spectrophotometer. The result shows that the R6G-doped [P(MMA:HEMA)] offers a good optical transmission and improved surface quality when compared to R6G-doped PMMA.
