PHOTOLUMINESCENCE OF NONSTOICHIOMETRIC CA DMIUM SELENIDE

We present a photoluminescence study of non-stoichiometric polycristal line cadmium selenide films. The films were grown by a technique combi ning the methods of close spaced vapor and hot wall deposition. The an alized films were deposited on silicon, quartz and glass substrates ma intaining the growth parameters fixed. The luminescence spectra of the films show emission mechanisms of common or similar origin thus refle cting the same kind of impurity/defect levels generated during the gro wth.
