Abstract

Laser irradiation effect on optical properties of Se88Te10Al2 thin film has been studied. Thin films have been prepared by physical vapor deposition technique using thermal vapor evaporation unit. Transmission and Absorption spectra has been taken by double beam UV-VIS spectrophotometer. He-Ne laser has been used as irradiation source. Optical Analysis of thin films indicate indirect allowed transition and the optical band gap (Eg) decreases with increasing irradiation time. It is also observed that laser irradiation of 30 minutes time interval changes all optical constant harmonically. Such irradiation effect can be utilize in device applications for laser activated switches and memories.
