Structural and Optical Properties of Zn1-xNixO Nanoparticles Synthesized by Co-precipitation Method

Abstract

Recently Ni doped Zinc Oxide Nanoparticle has worldwide research interest because it is considered a promising material for gas sensors. Although ZnO is one of the earliest discovered semiconducting Oxide gas sensing material. Nanocrystals of undoped and Nickel doped Zinc Oxide were synthesized by Co-precipitation Method. The Structural and morphological Properties were determined by X-Ray Diffraction Technique and Scanning Electron Microscope. The average particle size was determined from X-ray line broadening. X-ray study revealed that Ni doped ZnO crystal is hexagonal wurzite structure. The size of the particle depends on the dopant. The crystalline size of Nanocrystals varied from 11 to 16 nm as the calcinations temperature increased. The optical absorption of Ni doped ZnO indicated that it can be used as an efficient photo catalyst under visible light irradiation. The optical property is analyzed by photoluminescence analysis. It reveals that the emission wavelength and corresponding band gap energy is found to be 576 nm and 2.12 ev respectively. Another sharp peak is observed and it is in the wavelength of 584 nm and band gap energy is 2.15 ev and emits light in the region of yellow visible spectrum.
