Abstract
The infrared reflectivity spectra of mixed crystals of have been measured at 15 and 300°K. The infrared-active phonons occur in two main bands with frequencies near those of pure CdS and pure CdSe. Some features of the spectra are similar to the lattice vibrations in the system. The model used for that system is extended to the wurtzite structure. The main features of this model are the dependence of the phonon frequencies and strengths on concentration and on the short-range clustering of the cations around the anions. Compared with , the clustering behavior is found to be significantly less for the present system.
