Illumination of amorphous As2S3 film by ultraviolet light with an overall light intensity on the sample surface of around 10Wcm-2 leads to extensive film oxidation. After 2 min of illumination most of As2S3 film of an original thickness at around 0.425 µm was converted into a cubic form of As2O3 - arsenolite. A considerable amount of arsenolite microcrystals were found at a height of around 2µm and more which indicated a growth of As2O3 microcrystalline particles from the vapor phase.
