Abstract: The presence of metastable cubic modifications has been revealed by X-ray diffraction in polycrystalline CdS and CdSe powders with grain sizes on the order of several dozen nanometers. The optical reflection and photoluminescence spectra of the cubic CdS phase have been measured in the temperature interval of 77–295 K. The main exciton transition energies and the temperature coefficients of the bandgap width variation have been determined.
