| Abstract: | The optical absorption coefficient of
amorphous 40TeO2-(60-x) V2O5-xMoO3 thin films was
determined in a spectral range 190-1100 nm at room temperature. The fundamental
optical absorption edge was sharp. The optical gap generally increases as the
proportion of MoO3 in the mixed films increases. The width of the
tail of the localized states in the band gap was determined for different
compositions, which is because of the lack of long range order. The results of
the usual density-of-state models of amorphous materials are presented in this
paper. |
