Abstract
In this paper, the pulsed laser method was used to obtain silver nanoparticles, and one of the first signs indicating the production or generation of nanoparticles using the pulsed laser is the change in the color of the solution. In our study, deionized distilled water with a volume of 5 mL was used to prepare the samples with energy (300, 500)mj With pulsed (50, 100, 150, 200) pulse. We observed change in color of solution to a dark yellowish color that means obtained silver nanoparticles. In another side study the obsorbancy and transmission by using U-Visible spectroscopy, the peaks of all samples were at 400 nm this confirms that nanoparticles have been obtained. The mean energy gab calculated for direct transition allowed of the samples are 2.94 eV.
