AgO Nanoparticles Synthesis by Different Nd:YAG Laser Pulse Energies

Pulsed Laser Ablation in Liquid PLAL is one of the most effective methods for creating nanoparticles material. The PLAL process was used to make AgO nanoparticles, in which the silver target was submerged in ultrapure water UPW and then irradiated with an Nd: YAG laser (Q-switched, 1064 nm, 6 ns pulse duration). The laser beam was concentrated near the silver surface throughout this operation. The effects of different incoming laser pulse intensities (50, 250, 500, 750) mJ were investigated on the particle size of nanoparticles generated via laser irradiation. Nanoparticles in the nano solution were characterized through Atomic Force Microscope AFM, Ultraviolet-Visible UV-VIS test, PH measurement, and Electrical Conductivity EC test. The smallest particle size was produced with (50) mJ laser pulse energy. A new model is derived to understand the electrical conductivity results at different sizes including nanoscale. The new model brought a new factor proportional to the third degree of grain size. Despite the experimentally yielded low value compared with other factors, it has a valuable role in interpreting the conductivity results at different grain sizes.
