碩士 === 國立東華大學 === 材料科學與工程學系 === 93 === In this study, Arsenic chalcogenides As2(Se1-xSx)3 with x=0,0.2,0.4,0.8 and 1.0 were grown by Vertical Bridgman Method and vacuum evaporation method. The composition and crystalline structure of ternary compounds were investigated by EPMA and X-ray techniques. The molecular vibration mode and energy band gap of the whole series compounds were examined by Raman and transmission spectra measurements. The photodarkening effect in the amorphous As2(Se1-xSx)3 was discussed .
