t:The Au nanoparticles with different sizes were firstly synthesized and the Au@ZnO core shell nanostructure were subsequently prepared by the seed growth method. Using Tetraethyl orthosilicate (TEOS) as precursors, and the ZnO layer were etched, finally the Au@SiO2 Yolk/shelll particles were synthesized . The morphology, structure and stability properties of the samples were investigated by TEM and UV-VIS absorption spectrometer.
