Abstract:   (2696 Views)
Zinc oxide nanoparticles were synthesized using pulsed laser ablation of Zn metal plate in deionized water without using surfactant. In this paper, the effects of laser pulse energy and wavelength on the properties of ZnO nanoparticles have been investigated. Transmission electron microscopy analysis confirmed that the size distribution of ZnO nanoparticles is decreased with increasing the laser pulse energy. The room temperature photoluminescence spectra of ZnO nanoparticles show intense violet emission along with the emission in blue and green band. The excellent UV emission indicates that the ZnO nanostructure have a low defect concentration.
Keywords: Photoluminescence spectrum, Laser ablation, ZnO nanoparticles
