摘要：

The optical absorbance, refractive index and absorption edge of vapour deposited amorphous Sb2S3 films are studied systematically as a function of annealing temperature in the range 160 degrees C > T> 23 degrees C. As deposited films continuously loose sulphur above 60 degrees C as determined by ESCA and this loss affects their measured optical properties. Modification of optical properties upon heating to T = 160 degrees opens the possibility of a WORM (write once read many times) kind of optical storage as demonstrated in laser irradiation experiment.
