Abstract

ZnO:Mg nanocomposite formation by two-step laser ablation in deionized water is analyzed. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), UV–Vis spectroscopy, scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis were employed to obtain infrared spectra, crystalline structures, optical absorption spectra, morphology and spatial composition of the prepared nanocomposite. The FTIR result shows that bonds at ∼480cm−1 and 900cm−1 correspond to Zn–O and Mg–O stretching modes. The XRD pattern observed the hexagonal wurtzite of ZnMgO phase at 2θ=34.31∘ and 34.76∘. SEM image shows a flower-like hierarchical structure with a full array about 2μm. The absorption spectra demonstrate that a band gap of nanocomposite increases as the Mg content increases.
