Abstract:While the Lithium ion modification strategy is widely adopted in tuning the bandgap of semiconductors in dye‐sensitized solar cells (DSSCs), such strategy is yet to be applied to semiconductor‐based surface enhanced Raman scattering (SERS), which is also a photo‐induced charge‐transfer (CT) process. Here, a new DSSCs‐inspired modification method is proposed for TiO2 nanoparticles (NPs): through the adsorption of Li+, the surface states of TiO2 NPs are more abundant, so that the SERS intensity and charge transf… Show more
