Self-catalytic synthesis and photoluminescence property of cluster-like CdSiO3 nanowire arrays.
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.
