Synthesis of The gold Nanoparticles with Novel Shape via Chemical Process and Evaluating The structural, Morphological and Optical Properties

The results of this research have been indicated by Particle Size Analyzer analysis and the Scanning Electron Microscope show the size and the shape of the colloid of gold nanoparticles which find in the range of nanoscale about (20-40) nm. Zeta Potential measurements show the excellent stability of gold nanoparticles colloid at value (-33 mV). Optical properties studied the absorbance peak of gold nanoparticles colloid at (λ= 537.2) nm.
