摘　　要：In the presence of PVPK30,Cu 1-x Ag x I nanoparticles were prepared by ion exchange reaction.The product was char acterized by FT-IR,XRD,TEM,EDS and SPS,respectively.It was found that the value of x is ap-proximately0.5～0.6and the average diameter of the nanopa rticles is10～20nm.The product shows surface photovoltage property of semic onductor and the existence of Cu + greatly enhances the separation efficiency of photoinduced electron-hole pa irs.Meanwhile,SPS of Cu 1-x Ag x I nanoparticles with different X(Ag/I)value had been investigated.The re sults show that when X is0.5～0.576,the SPS intensity of Cu 1-x Ag x I nanoparticles is highest.In the presence of PVPK30,Cu 1-x Ag x I nanoparticles were prepared by ion exchange reaction.The product was char acterized by FT-IR,XRD,TEM,EDS and SPS,respectively.It was found that the value of x is ap-proximately0.5～0.6and the average diameter of the nanopa rticles is10～20nm.The product shows surface photovoltage property of semic onductor and the existence of Cu + greatly enhances the separation efficiency of photoinduced electron-hole pa irs.Meanwhile,SPS of Cu 1-x Ag x I nanoparticles with different X(Ag/I)value had been investigated.The re sults show that when X is0.5～0.576,the SPS intensity of Cu 1-x Ag x I nanoparticles is highest.
