EFFECT OF ANNEALING TEMPERATURE ON STRUCTURAL AND OPTICAL PROPERTIES OF CHEMICALLY DEPOSITED BISMUTH SULPHIDE THIN FILMS

摘要

Bismuth sulphide thin films have been prepared onto amorphous glass substrates by chemical bath deposition method at bath temperature of 333K using bismuth nitrate, sodium thiosulphate and EDTA as complexing agent. The deposited films are characterized by X-ray diffraction and optical absorption. The effect of annealing on the structural and optical properties is studied.
