Effect of Introduction Style of Ag Nanoparticles on SERS Properties of TiO2 Three-dimensionally Ordered Porous/Ag Composite Nanostructures
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
2
nanostructure (TiO
2
-3DOM) and investigated the influence of the way to combine Ag nanoparticles with TiO
2
-3DOM on its SERS performance. The results tell that TiO
2
-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.
