Abstract

The homogeneity of solid solutions of cadmium selenide and cadmium sulfide has been investigated. Crystals of the solid solutions having different selenium contents were grown in the Aerospace Research Laboratories by the conventional methods as described in the earlier conferences. The composition of these solid solutions were analyzed chemically for their selenium content by a procedure perfected in the Aerospace Research Laboratories.

Crystals in the form of lumps were cut to optimum size suitable to be inserted into the commercially available sample holder. The selenium content of these crystals was ascertained by scanning the samples with stationary colljmators of small aperture. The spectrograph used for the present study was operated at 75 KVP and 50 mA. The target tube was constructed of molybdenum. The results from the chemical method were used to correlate the counts per second obtained from the X-ray spectrograph.
