Zinc Selenide has been synthesized through hydrothermal method using Zinc Acetate Dihydrate (Zn(O2CCH3)2(H2O)2) and Se powder as the precursor. In a typical synthesis, Zn2+ and Se2- ion have been prepared separately and charged into a teflon-lined stainless steel autoclave. The ZnSe are characterized by X-ray diffraction (XRD), Field Emission Microscopy (FESEM), ultraviolet–visible spectroscopy (UV-Vis) and photoluminescence (PL). From the Pure ZnSe with main XRD peak at 2θ = 27.29°, 45.30°, 53.62°, 65.88°, 72.68° has been synthesized with the optical band gap energy (Eg) of 2.50 eV with emission peak at 486 nm.
