On the synthesis of Au/ core-shell structure nanoparticle, the effect of concentration of and reaction temperature on the morphology and optical property of Au/ core-shell nanoparticles is examined. A gold colloid was prepared by . Titanium stock solution was prepared by mixing solution of titanium(IV) isopropoxide (TTIP) and triethanolamine (TEOA). The concentrations of stock solution were adjusted to mM, and then the gold colloid is added to the stock solution. Au/ core-shell structure nanoparticles could be prepared by the hydrolysis of the stock solution at . The size of synthesized Au nanoparticles was 15 nm. The thickness of shell on the surface of gold particles was about 10 nm. The absorption peak of synthesized Au/ core-shell nanoparticles shifted towards the red end of the spectrum by about 3 nm because of the formation of shell on the surface of gold particles. The good shell is produced when concentration is varied between 0.01 and 0.05 mM, and reaction temperature is maintained at . The crystal structure of shell was amorphous.
