UV Emission from Patterned Growth of ZnO Nanowires
Patterned and high-density ZnO nanowires were fabricated on a large area P type silicon (100) through Vapor–Liquid–Solid approach. An aluminium mask was used for the patterned deposition of gold catalyst. ZnO nanowires grown with the aid of gold catalyst were well aligned and had dimensions of 30–80 nm diameter and 0.5–2 m length. The perfect crystallinity and orientation  of the nanowires were confirmed by high-resolution transmission electron microscopy (HR-TEM). Low-temperature photoluminescence spectrum exhibits an intensive UV emission at ∼380 nm and a weak broad green band at ∼530 nm which is detected under an optical excitation of 325 nm wavelength of He-Cd laser. These arrays of ZnO nanowires could have myriad applications in nano-lasers, optoelectronic devices and optical interconnects.
