Abstract

Abstract : The population of surface-trapped electrons determines the SERS performance of a W18 O49 substrate, as proved by construction of metal–semiconductor or organic–semiconductor interfaces. Abstract : The population of surface-trapped electrons is found to be in a close relationship with the SERS performance of a nanostructured W18 O49 substrate, as proved by construction of metal–semiconductor interfaces or organic–semiconductor coordination. Therefore, further improvement in the SERS performance of semiconductors could be expected by populating the surface-trapped electrons.
