Abstract

The SnO₂-CdS type structures with SnO₂ film deposited by thermal pirolize in SnCl₄-etanol solution were obtained. The CdS film with submicron thickness was obtained in cvasiclosed volume. The transversal section of the SnO₂-CdS junction as well as the outer surface of the CdS film was analyzed using the electronic microscope. The density of the crystallization germs in the CdS film was about 10¹³cm^-2. The luminescence spectrum of CdS has been examined. The existence of exciton line (n=1) in reflection and emission spectrum serves as a criteria of crystalline perfection of surface film.
