The authors investigate the optical absorption spectra and the photoconductivities of anodic oxide film based on GaAs, GaP, and GaAs/sub 0.6/P/sub 0.4/ in the range of light energy quanta 2-6.2 eV. Anodic oxide film (AOF) was studied on the surface of single crystals of GaAs and epitaxial layers of p-type Gap and AsAs/sub 0.6/P/sub 0.4/ of the n-type. The structures of the oxides were monitored by electron diffraction. The photoconductivity of the AOF was investigated. The absorption of the AOF in the visible and near-UV ranges was estimated by comparing the spectra of excitation of photoluminescence at 80 K for specimens coated with an AOF and specimens with the AOF removed by etching in HCl.
