OPTICAL PROPERTIES OF ZINC SULPHIDE (ZnS)

Optical properties of Zinc Sulphide (ZnS) have been investigated by means of Kramers Kronig method. Optical properties such as refractive index, extinction coefficient, dielectric constant, transmittance, absorption coefficient, reflectance, reflection coefficient and optical conductivity are presented in the energy range 0.60 – 6.01eV. The calculated optical properties of ZnS indicate that it has promising applications in the fabrication of optoelectronic devices such as phosphors and catalysts, laser, sensor, infrared windows, the cathode ray tube, solar cells, blue light-emitting diodes, electro-optic modulators, electroluminescence device applications and Light emitting diodes (LED).Â
