Abstract: | CdS single crystals which were not specially doped and which were doped with copper (N Cu=1018 cm−3) have been investigated. It is concluded on the basis of an analysis of the dose dependences of the orange luminescence intensity (λ M=605 nm) of “pure” and doped samples upon bombardment by electrons with E=1.2 MeV and by fast reactor neutrons that the centers responsible for this luminescence are complex in nature. They consist of interstitial cadmium atoms and oxygen atoms. Electron bombardment of CdS:Cu single crystals results in the formation of new centers which are responsible for luminescence with λ M=570 and 545 nm. Fiz. Tekh.
