Abstract
Thin films from bismuthinite Bi2S3 and guanajuatite Bi2Se3 and their mixture Bi2S3xSe3(1-x¬) were prepared by vacuum evaporation under low vacuum (10-5 torr) on clean glass substrates at 300 oK. X-ray diffractions are studied to show that all films as-deposited have been amorphous structure and become polycrystalline after annealing at 533 oK. They have rhombohedral structure at compositions (x=0.0,0.2,0.4,0.6) and orthorhombic structure at (x=0.8,1.0). Optical properties are studied includes determinations of absorption coefficient from the absorbance, transmittance spectrum range (300-900)nm and estimation of energy gaps before and after annealing which was (1.75-1.84) eV and (1.74-1.7) eV respectively and their mixture is about between these values.
