Thin films of Sb2S3 were prepared by flash evaporation. As-deposited films were found to be amorphous and highly resistive (R>106Ω) in nature. An amorphous-crystalline phase transition occurs at 498 K on subsequent annealing in nitrogen atmosphere. The fundamental optical transition is direct in nature and the optical band gaps (Eg) lie in the region 1.70–2.07 and 1.42–1.65 eV for amorphous and crystalline films, respectively. A near-linear decrease in Eg with decreasing S/Sb ratio was observed suggesting the dependence of the band gap on film composition.
