The II - VI semiconductors, such as Zinc Sulphide (ZnS) have attracted growing interest owing to their possible application in electro-optic device, it is important semiconductor material for the development of various modern technologies of solid - state devices. Zinc Sulphide have wide direct band gap of about (3.50 -4.1) eV in the UV region; it is used as a key material for blue light emitting diodes and other optoelectronic devices such as cathodluminescent displays , multilayer dielectric filters, electroluminescent displays and multilayer dielectric filters. Zinc Sulpide is highly...
