Synthesis and analysis of gold nanoparticles produced by laser

Abstract Gold nanoparticles are produced by employed nanosecond pulses of Nd:YAG laser using laser ablation process in liquid. The two systems used are Nd:YAG of 6 and 10 nanoseconds pulse duration with variable energy in the range (700-760 mJ ). The formation of gold nanoparticles has been rerealed using TEM with uniform size distribution. Also, it has been discovered that the mean nanoparticles sizes of 70 and 100 nm for gold respectively when similar laser parameters are used. In addition, theoretical Mie-Gans model was used to estimate the temperature distributions for both gold nanoparticles. Another aspect that has been discovered is that the maximum temperature of about (40 k K° ) and (60 k K°) for gold nanoparticles, especially to prepare nanoparticles in the presence of Nd:YAG of 10 ns.
