Abstract

Pulsed laser ablation in liquid (PLAL) technique has been used to synthesize ZnO and ZnO-Mg nanoparticles by conducting laser ablation of zinc target in pure water and Mg(NO3)2 solution. The absorbance spectra show redshifted peaks of ZnO with Mg inclusion indicating the lowering of the band-gap energy down to 3.09 and 3.01 eV from 3.28 eV of the pure ZnO. The higher frequency visible emission peaks of ZnO-Mg in the photoluminescence spectra indicate more recombination due to the formation of Mg interstitial state. The XRD measurement shows the diffraction of ZnO-Mg shifted into lower peak, resulting longer interplanar spacing, which matches to those obtained from HRTEM measurement.
