Abstract: A systematic study of the infrared photoluminescence from deep centres in polycrystalline CdSe layers is presented. The authors observe two emission bands at about 0.92 mu m and about 1.22 mu m. The evolution of the band shape and emission intensity quenching with temperature is analysed using a semiclassical model, and the characteristic parameters of the centres are obtained. The results are shown to be consistent with transitions involving selenium vacancies VSe and oxygen impurities OSe. © 1988 IOP Publishing Ltd.
