Abstract EN

Colloidal nanoparticles attended with a pulsed Nd:YAG, Q-switch in water distilled at wavelength (1064nm) and frequency rate (1Hz) and pulse duration (10ns) and silver nanoparticles attended without the use of surface tensile as laser removal of the silver target (10ns) was attended by silver nanoparticles without the use of surface tensile as laser removal of the silver target (10ns) was attended High purity) reached purity (99.9) immersed in distilled water (deionized) where the metal target was first removed from silver placed in (5mL) from distilled water, a specific laser card (260mJ) and a number of pulse fixed laser pulses(50, 100, 150) respectively, where the size and optical characteristics of nanoparticles were distinguished by the powerful electron microscope (TEM) and visible UV spectrometry (visible-UV), respectively, and the peaks of surface plasma resonance (SPR) showed an increase at (403) and (405) Nm, which is therefore within the permitted range, showed a higher peak of 405 nm and showed sharp spectra, although the width of the spectra slightly increased and the energy gaps showed an increase in the amount of 2.54eV at pulse (50).

And (2.57eV) at pulse (100) and valued (2.66eV) at pulse (150).
