Preparation of silver nanoparticles by pulsed laser ablation in liquid medium

Abstract

In present work Silver nonoparaticles have been prepared by using pulsed laser ablation ( Q -switched Nd:YAG) 1064nm  pluse duration and(E= 100mJ to 400mJ  ) of pure Ag mateal plate immersed in distilled water and dionized water  .The synthesized nanoparticles are characterized using transmittance electron microscopy (TEM) and UV-VIS spectrophotometer . The effect of the pulses energies and number. of shots have been reported .The silver nanoparticles exhibited asurface Plasmon resonance effect with wave length (λ_spr=400nm).The production of pure and spherical Ag with average size of (1-15nm) .All the size measurements have been confirmed by TEM.
