Abstract

Amorphous Te_xAs₄₀Se_60-x (x = 0, 10) thin films were prepared using thermal evaporation technique onto cleaned glass substrate at room temperature, and then exposed to UV-VIS light (having accordance with ASTM standards CIE 85 Table 4) using a Xenon lamp for two hours duration. Thicknesses of the films were measured using a stylus based surface profilometer. Structural analysis of the films was done using XRD measurements. Optical changes under UVVIS exposure were investigated by UV/VIS spectroscopy in wavelength range 300~900 nm. Changes in optical parameters are proposed for environmental monitoring applications. These results are compared with other range of photoexposures for some different Te-As-Se compositions in order to analyze their usability for various photonic applications.
