CdS Nanoparticles Synthesized by Laser Ablation in Liquid
摘要
Abstract—Cadmium sulfide (CdS) nanoparticles synthesized by the method of laser ablation in liquid are experimentally studied. The structure, surface morphology, and optical properties of the nanoparticles are examined using X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy. Based on analysis of the absorption and photoluminescence spectra, the band-gap width (eV) and the nature of the emission generated in the nanoparticles under the influence of a Nd:YAG laser are determined.
