Abstract :

The nanoparticles of gold doped with various percentage of copper (Cu 10%, 25%, 75%) were synthesized by wet-chemical method at room temperature. Copper (II) sulfate and gold (III) chloride trihydride was taken as the metal precursor and ascorbic acid as a reducing agent and anhydride maleic as surfactant. The reaction is performed with high-speed stirring at room temperature under nitrogen atmosphere. X-ray diffraction (XRD), Scanning electron microscopy (SEM) and DRS UV-Vis spectroscopy have been used for the characterization of the samples. Moreover the X-ray diffraction results indicated that the synthesized Cu doped Au nanoparticles had a pure single phase face-centered cubic structure and the average particle sizes were between 5.43 - 12.6 nm. SEM images shows a spherical shape and dopant Cu influenced the particles size of the powder.
