Structural, optical and electrical properties of luminescent (ZnS) 1− x (MnTe) x powders
Intense photo and mechanoluminescent (ZnS) 1− x (MnTe) x powder samples with x = 0.02, 0.05, 0.10, 0.15, 0.20 and 0.25 were prepared by simple solid state reaction method. All samples were polycrystalline with wurtzite structure. Wurtzite lattice parameters increased with composition ‘ x’ linearly o...
