摘要：

Pure and Zn-doped TiO2 nanoparticles were prepared by a sot-hydrothermal method and employed as surface-enhanced Raman scattering(SERS)-active substrates. The relationship between photoluminescence performance and SERS effect of TiO2 nanoparticles as well as photoluminescence mechanism were mainly investigated. The results indicate that surface properties of TiO2, such as surface defects and oxygen vacancies, etc, play important roles in the PL and SERS. When the contents of surface defects and oxygen vacancies are relatively low, the stronger is PL signal of TiO2 nanoparticles, the higher is SERS performance; however, when the contents of surface defects and oxygen vacancies are relatively high, the weaker is PL signal, the higher is SERS performance.
