ABSTRACT: Chemical modifications by incorporating organic dye molecules in polymethylmethacrylate (PMMA) matrix may open up the possibility of the development of smart materials. In the present work, Kiton red-620 laser dye is embedded in synthesized PMMA matrix by chemical doping process. The spectral investigations of Kiton red-620 doped PMMA matrix has been carried out using FTIR, UV-visible and photoluminescence spectrophotometers. FTIR study showed that the absorption band region 1800 - 1000 cm-1 becomes sharper with the concentration of dye in PMMA matrix. UV-visible and photoluminescence study showed that a slight shifting appears in the absorption spectra, emission spec- tra and intensity of emission peaks as concentration of dye increases in PMMA matrix.
