摘要
The ZnO nanowires were synthesized using vapor liquid-solid (VLS) growth process on copper coated p-type Si (100) Substrate. Copper catalyzed the growth of ZnO nanowires of diameters 80-150 nm and lengths of 2.5-4.0 mum. The ZnO nanowires had hexagonal structure and exhibited <0002> 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. (C) 2002 Elsevier Science B.V.
