| Abstract | Theoretical and experimental investigations on the optical behavior of thin films mainly deal with band gap, optical reflection, transmission, absorption and their relation to the optical constants. The optical transmittance spectra are recorded from 100 to 1000nm wavelength using a Hitachi UV-VIS-NIR spectrophotometer (Model-JASCO V-570) using a doped Azopolyester thin films were observed. Unpolarized radiation at room temperature with a resolution of 2nm was used in this study. Unpolarized radiation at room temperature with a resolution of 2nm was used in this study. The measurements were made on films of typical uniform thickness of 5μm deposited on glass substrate. The substrate absorption was corrected by introducing an uncoated cleaned glass substrate in the reference beam. The study of optical absorption / transmittance is a useful method for the investigation of optically induced transitions which provide information on the band structure and energy gap in both crystalline and non-crystalline materials. Finally optical applications of doped Azopolyester in fiber optic cable were used in telecommunication is discussed. |
