“…ZnS can be used for the fabrication of optoelectronic devices such as blue-light emitting diodes, electroluminescent devices, electro-optic modular, optical coating, n-indo layers for thin film heterojuncion solar cells, photo conductor, and photo voltaic devices [5][6][7][8]. It is used in beam splitting and band pass filters over the region between 400 and 1000 nm [9][10][11]. Because of its high refractive index (2.35), and a dielectric filter, it is used as reflector in the visible region [12].…”
