Abstract : Cadmium sulfide and zinc selenide were synthesized. Impurities present in these and in zinc sulfide were determined by mass and emission spectrography and by the atomic absorption method. Purities of the zinc compounds are generally lower than that of the CdS. The growth of crystals of II-VI compounds from the melt was continued. A number of custom doped crystals of ZnS, ZnSe, and mixtures of the two were grown. The light transmission characteristics of a ZnSe specimen were determined from a spectrophotometric plot. The crystal slice used for a window in this experiment, exhibited a pattern of interesting imperfections from which some of the crystal growth conditions might be deduced. Cadmium sulfide crystals were grown routinely by the method of vapor phase deposition.
