Abstract
Systematic studies of the refractive index, extinction coefficient, and optical band gap have been made of as-grown and UV-exposed amorphous films of As2S3 grown by thermal evaporation from resistive source. The refractive index and extinction coefficient have been found to change with different UV exposure duration. No noticeable change was observed in the optical band gap with UV exposure.Keywords
