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.
