Abstract

Abstract: This research aims to understand the influence of ZnO and NiO molarity towards its optical and morphological properties. ZnO/NiO was synthesized using solvothermal method with ZnO and (Ni(NO)3 )2 .6H2 O as its main ingredients and dissolved in ethanol. The synthesis of ZnO/NiO using solvothermal method was carried out by modifying the variation of ZnO concentration with the ratio of ZnO and NiO were 1:1, 2:1, and 3:1. ZnO/NiO was used as a semiconductor material which will be analysed for optical properties that occur, one of which was band gap energy. The result was then characterized by X-Ray Diffraction (XRD) showed that the crystal size of the sample at 3:1 is the largest. Furthermore, the Fourier Transform Infrared Spectroscopy (FTIR) analyst indicated that the sample corresponds to C=C and C-H bonds. Moreover, the UV – Vis analyst showed that the absorption range is between 300-400nm indicated the extended UV-Vis absorption property of mixed oxide.
