Preparation and Study Physical Properties of Metallic Ag, Au, and Zn Nanocomposite Colloidal Nanoparticles via PLAL method

In this work, silver, gold, and zinc nanoparticles were prepared and then mixed to obtain silver, gold, and zinc nanocomposites easily and simply using an Nd:YAG laser. They were prepared using the pulsed laser ablation in liquid (PLAL) method to investigate the effects of different solutions on the properties and size of nanoparticles at constant energy (520 mJ) and the number of pulses (2000 for Ag and Au and 4000 for zinc) using the laser with a wavelength of 1064 and a frequency of 1 Hz. The results were analyzed The results were analyzed using XRD, single crystalline phase cubic for AgO nanoparticles, cubic crystalline system for AuNP, and crystalline phase with a cubic structure for ZnO nanoparticles, while determining UV-visible peak SPR the nanoparticles at 399 nm for AgO nanoparticles, at 524 nm for Au nanoparticles, and at 301 nm for ZnO nanoparticles, and the energy gap of the nanoparticles was determined. Studying and preparing these nanoparticles is very useful in medical and industrial applications.
