Au and Ag NPs were separately prepared in PVP solution by laser ablation. The mixture of Au and Ag NP colloids was irradiated by the second harmonic (532nm) of pulsed Nd:YAG laser with different laser fluencies and exposure times. The Plasmon resonance absorption spectrum, morphology and structure of Au-Ag alloy NPs were observed by a UV-2450 spectrometer (Shimadzu), a high resolution transmission electron microscope (TEM Tecnai G2 20 S-TWIN/FEI). The results show that the resulting Au-Ag alloy NPs are homogeneous alloyed particles and dispersed in PVP solution with average diameter of 4nm without sintered structure. Au-Ag alloy NPs were produced by 532nm laser with different Au/Ag molar ratio of the initial mixed solution to give the plasmon resonance absorption peak in the intermediate positions between about 420 and 520nm.
