Abstract: (1598 Views)
Considering the effects of low dose Gamma radiation on nanoparticles in this paper gold and silver with 0.05 and 0.005 concentration have been synthesized in two ways, chemical reduction and radiation of gamma source Co-60 with total dose 4.79 (mGy). And then Optical properties are obtained by using Visible Spectroscopy for linear characterization. for gold absorption peak is around 530(nm) and silver peaks around 400(nm) and surely red-shift was seen for nanoparticles which prepared with Gamma. Also we use z-scan for nonlinear refractive and absorption index that shows the sign and order of indexes for absorption index is in order of 
(cm/W)and for refractive index is in order of 
( 
/W).The results indicate better performance in chemical and optical features of nanoparticles with low dose Gamma radiation.
