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(NO 3 ) 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.
