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...

Summary: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 V S for crystals with a hexagonal (wurtzite) lattice. Light output of ZnSe 1- x S x crystals increases with increasing the sulfur content up to x = 0.3 and reaches the value of light output observed for ‘classic scintillator’ ZnSe(Te). At the same time, the ZnSe 1- x S x bulk crystals possess better thermal stability at the same energy of emitted photons ( hν ~ 2 eV) as compared to that of the ZnSe(Te) crystals.
