| 摘 要： | In the presence of PVPK30,Cu1-xAgxI nanoparticles were prepared by ion exchange reaction.The product was characterized by FT-IR,XRD,TEM,EDS and SPS,respectively.It was found that the value of x is ap-proximately 0.5～0.6and the average diameter of the nanoparticles is 10～20nm.The product shows surface photovoltage property of semiconductor and the existence of Cu+ greatly enhances the separation efficiency of photoinduced electron-hole pairs.Meanwhile,SPS of Cu1-xAgxI nanoparticles with different X (Ag/I)value had been investigated. The results show that when X is 0.5～0.576, the SPS intensity of Cu1-xAgxI nanoparticles is highest.
