Z. L. Zhang, D. N. Li and Y. L. Mao Effects of trap density on the surface-enhanced Raman scattering of molecules adsorbed on TiO2 (Degussa P25) Journal of Raman Spectroscopy 43
The variation of SERS intensity with the calcination temperature rising was observed with TiO2 (Degussa P25). The trap density of TiO2 was directly measured. The increase of trap density is favorable for the increase of SERS intensity.
