The growth, structure and luminescence properties of ZnSe1-xSx materials
ZnSe 1- x S x crystals with a higher content of selenium or sulfur ions adopt, respectively, a wurtzite or sphalerite structure. Luminescent properties of ZnSe 1- x S x crystals are determined by ternary V Zn Zn i O Se complexes for crystals with a cubic (sphalerite) lattice, and by sulfur vacancies...
