Abstract
Our purpose in this research work is to be synthesized Se75Te22In3 and Se75Te19In6 chalcogenide alloys which have been synthesized by using melt quenching method. Physical vapor condensation technique (PVCT) was used to prepared nano-thin films of synthesized Se75Te22In3 and Se75Te19In6 alloys. From HRXRD measurement clear that prepared thin films have amorphous texture. The morphological studies using FESEM suggest that the nanochalcogenide thin films contain particles of size ranges from 30–60 nm. Based on UV–Visible spectroscopy studies, absorption coefficient (α) is found to increase with photon energy and had significant change due to the change in Indium concentration. The optical absorption obeys rule of direct transition. Optical band gap increases from 2.18 to 2.22 eV when Indium content increases. These studies suggest that our prepared materials have possible application in different optical and storage devices.
