Abstract : The following advances were made toward a practical II-VI solid-state light source: Preparation procedures of starting material and growth techniques for II-VI crystals and epitaxial films from melt, solution and vapor, were improved. Highly p-type ZnSe films were prepared. The melting point - composition diagrams of ZnTe and ZnSe were established and the first n-type ZnTe crystals prepared. New types of electroluminescent junctions were found such as the physical inversion layer and the ZnSe-ZnTe quasihomo-junction. The luminescence due to rare-earth ions in ZnSe and ZnSexTe(1-x) crystals was studied. The change of luminescence in ZnSxSe(1-x) mixed crystals was explained in a theory that is generally applicable to the luminescence of mixed crystals. A partial understanding of the phenomenon of self-compensation was gained and new approaches to fight it were devised. The general concept of II-VI electroluminescence was clarified and the problems defined. (Author)
