The spectrophotometric method determines two absorption and reflection spectral areas of nanosize MoO3 layers - short-wave λ<330 nanometers and long-wave λ>330 nanometers. It is stated by spectrophotometric, gravimetric and microscopic methods that in atmospheric conditions MoO3 layers transformation degree (d=10...130 nm) grows at time (1...140 minutes) and heat treatment temperatures (Т=373...600 К) (at constant layer thickness) increasing as well as at reduction of layers thickness. The reduction of absorption maxima at λ=350 nm and increase at λ=870 nanometers at heat treatment of MoO3 layers is revealed. The colour centers formation model is offered. It includes the center formation - anionic vacancy with one seized electron ([(Vа) ++ е]) during preparation of MoO3 layer, thermal electron transition from a valent zone on a level of the center, the second electron capture by the center ([(е Vа) ++ е]).
