| Abstract: | The optical properties of thin films of red Sb2S3 prepared by vacuum evaporation on amorphous substrates were determined from transmission measurements. The variation of the extinction coefficient,K, shows structures at energies of 4.4 and 5.4 eV. The band gap was found to be 1.7 eV for film of thickness 56 nm, and increase with thickness. The interpretation of structure was inferred from transmission electron microscopy and X-ray diffraction for thin films of antimony trisulphide. The investigated film thicknesses were from 46 to 64 nm. |
