三维多孔/Ag复合结构SERS性能的影响。研究表明，通过银镜反应得到的TiO

Abstract

Surface-enhanced Raman spectroscopy(SERS) is a high sensitive detecting technology

which is very promising in chemical and biological analyzing applications. Noble metals which own the unique characteristic of localized surface plasmon resonance and the substrates are two important factors. In this paper

we used PS (polystyrene) spheres as templates to fabricate three-dimensionally ordered TiO

nanostructure (TiO

-3DOM) and investigated the influence of the way to combine Ag nanoparticles with TiO

-3DOM on its SERS performance. The results tell that TiO

-3DOM/Ag obtained through silver mirror reaction is a very sensitive substrate

its detecting limitation to Rhodamine 6G (R6G) can reach 10

-10

mol/L.
