The Preparation and Properties of Cobalt-Doped 2-6 Chalcogenides

Abstract

Samples of cobalt-doped ZnS, ZnSe, and Cds and CdSe were prepared by the direct combination of the elements. The limit of solubility of cobalt in these systems was established. Magnetic measurements indicate that the antiferromagnetic interactions of the cobalt in the zinc systems were greater than those observed in the cadmium chalcogenides. Single crystals of cobalt-doped zinc chalcogenides were grown by chemical vapor transport. Their IR transmission was measured and the cobalt concentration for maximum hardness was determined.Keywords: Solid State chemistry; Zinc sulfide; Cadmium sulfide. (JES)
