CaV0.5Mo0.5O3 − δ with the structure of perovskite is synthesized in an atmosphere of humid hydrogen. It is found that when the material under study is moved into air, a nonequilibrium state forms due to the enhanced concentration of oxygen over the surface of the highly reduced oxide. It is shown that photoinitiated oxidation is observed on the surface of the material under the action of a low-power laser beam (50 mW), where it selectively occurs under a green laser beam (λ = 532 nm). This phenomenon is observed for such materials for the first time.
