Abstract
In this research work, a pulsed Nd-YْAG laser having a wavelength of 1064 nm and energy (400-700 mJ (has been utilized as a source in an induced breakdown spectroscopy (LIBS) experiment to determine the density of electron and the tem-perature of Ag-plasma. Two forms of silver (as a bulk and as a compressed nano powder) have been used as targets in the LIBSs setup. The aim of the present work is to study the impact of target properties and laser energy on the plasma fea-tures formed by the interaction between a pulsed laser and these two forms of silver. The structural properties have been characterized via X-ray Diffraction (XRD), Scanning Electron microscopy (SEM) and Energy Dispersed X-Ray Spec-troscopy (EDX). For the two forms of silver, the electron density and the temperature increased with the laser energy rise from (400 mJ) to (700 mJ), and the Ag samples in the form of nano particles manifested enhanced LIBS signals. More-over, the LIBS technique can give complement information to other standard techniques for the material's diagnosis.
