Abstract

Au nanoparticle decorated α-Fe2O3 NWs exhibit enhanced band gap luminescence due to coupling between excitons in α-Fe2O3 NWs and the surface plasmons of Au particles. The enhanced magnetization in α-Fe2O3 NWs with Au coating is attributed to the interfacial effects arising from the trapped metallic electrons at the Au/α-Fe2O3 NWs interface.
