摘要：

The key to sensitive detection using surface-enhanced Raman spectroscopy (SERS) lies in the optimization of the enhancing surface. Silver is often used because of its nearly ideal surface characteristic, ease of preparation as well as for excitation with accessible wavelengths. The polycrystalline Ag deposition on TiO2 by photo-induced reduction of Ag+ at the TiO2 surface found that under appropriate illumination conditions SERS-active Ag can be formed on photochemically active TiO2.
