Abstract

Abstract In this research, we study the effect of changing of Laser parameters on properties of lead sulphide thin film (PbS) nanoparticles prepared by Pulsed laser deposition (PLD) on the base of glass.We used pulsed laser deposition for the preparation of (PbS) nanothinfilm limits 70-85 (nm) using a pulsed laser (Nd-YAG) with a wavelength of 1064 (nm). examination of the atomic force microscope (AFM) and examination of scanning electron microscope (SEM) for thin films prepared in this way. The results showed the possibility of preparation of thin films with grain size around 75 (nm). The scanning electron microscope images showed and the formation of a spherical shape nanoparticles using the method of Pulsed laser Deposition (PLD)
