NanotechnologyV 1505 Aligned Zn—Zn2SiO4 Core—Shell Nanocables with Homogeneously Intense

Ultraviolet Emission at 300 nm. — The title nanocables, which exhibit uniform and strong middle-UV (300 nm) emission at room temperature are grown on Si substrates by vapor phase oxidation of metallic Zn powders. The lenghts of the nanocables in-crease as the distance between the substrate and the source decreases. The uniform Zn core certainly will bring about a unique kind of metal—semiconductor contact in each direction. The optical and expected electrical properties of the nanocables should gen-erate exciting advances in the applications of the material in optoelectronic devices. — (FENG, X.; YUAN, X.; SEKIGUCHI, T.; LIN, W.; KANG*, J.; J.
