Self-Catalytic Synthesis and Photoluminescence Property of Cluster-Like CdSiO3 Nanowire Arrays
Abstract:Cluster-like cadmium silicate (CdSiO3) nanowire arrays on Si substrate have been synthesized via a self-catalytic growth using a modified vapor-phase evaporation method. XRD and HRTEM analyses indicated that the CdSiO3 nanowire had a monoclinic single-crystal structure. The growth mechanism of the cluster-like nanowire array is proposed as vapor-liquid-solid mechanism, in which lower melting point Cd serves as the catalyst. The PL measurements revealed the strong photoluminescence peaks in the purple region of 358–476 nm due to the self-activated luminescence, which was different from those of CdSiO3 bulk powder.
