The ZnO nanowires were synthesized using vapor-liquid-solid (VLS) growth process on copper coated p-type Si (1 0 0) substrate. Copper catalyzed the growth of ZnO nanowires of diameters 80-150 nm and lengths of 2.5-4.0μm. The ZnO nanowires had hexagonal structure and exhibited 〈0 0 0 2〉 orientation. The photoluminescence measurements showed that the ZnO nanowires had a strong ultraviolet emission at around 381 nm and a very weak green emission around 520 nm.
