Ag-decorated TiO2 nanograss for 3D SERS-active substrate with visible light self-cleaning and reactivation†
Abstract
The production of SERS-active substrates which are uniform, sensitive, reproducibile and durable still remains an important issue. Here, we report a strategy for the fabrication of a large-area Ag-decorated TiO2 nanograss SERS-active substrate by a simple solvothermal approach combined with Ag
