Electrically conducting photoluminescent films have been prepared by evaporation onto suitably cleaned, heated sapphire ( orientation) substrates. The presence of electrical conductivity is shown to be correlated with (a) the degree to which the (111) planes of the films are parallel to the substrate surface, and (b) preferred orientation of these planes about the normal to the substrate. Crude electroluminescent comb cells utilizing these films have been fabricated.
