Abstract

The degree of the transformation of MoO3 films (d= 8–130 nm) increased as the duration (1–140 min) and temperature (373–573 K) of thermal treatment grew and as the film thickness decreased under atmospheric conditions. The thermal treatment of MoO3 films decreased the optical density at λ = 350 nm and caused the appearance of an absorption maximum at λ = 870 nm. A mechanism of thermal transformations of MoO3 was suggested. The mechanism included the formation of the [(V a)++e] center during the preparation and thermal treatment of MoO3 films and thermal electron transition from the valence band to the [(V a)++e] center level with the formation of the [e(Va)++e] center.
