Abstract
Disclosed is a method for improving the photo-induced discharge characteristics of certain cadmium chalcogenides selected from the group of CdS, CdTe, CdAs, CdSe and CdSSe. The method involves calcining a mixture of the cadmium chalcogenide or a precurser thereof in the presence of cadmium oxide or a compound which decomposes upon heating to cadmium oxide in an amount sufficient to provide an excess of unreacted cadmium oxide after calcination.
