Abstract:
ABSTRACT The present research describes the synthesis of Cu nanoparticles composite with SiO2@Au particles and absorption properties by chemical methods for different cases.The synthesis was made in two steps, in the first, SiO2 nanoparticles were coated with Au by using Stober method.The second step involved the production of silica-coated Au-Cu particles by changing the amount of NaoH and reaction time.The result shows that variationof the amount of NaoH led to absorption transform in the same reaction time, and when fixing the amount of NaoH and alteringreaction time, the absorbance properties changed. On the other hand, when absorbance increased and had a peak with the increase inreaction time in one case and another case. we had the opposite . Keywords : Nanoparticles, Absorption, Composite SiO2@ Au-Cu
