The crystallinity and composition were investigated by X-Ray, SEM, Raman and EPMA. The energy band gaps of crystals were examined by transmission measurement. The composition dependence of crystallinity, band gaps for As2(Se1-xTex)3 were discussed. Finally, the values of energy band gap (Eg) of glassy alloys with various composition (x) can be fitted by an analytical expression, and the result is Eg (x)=0.66x2+0.04x+0.82 Ching-Cherng Wu 吳慶成 2007 學位論文 ; thesis 84 zh-TW
