The ZnO nanorods grown on in-situ synthesized ZnSe grains through the chemical vapour deposition method are reported here for the first time. With a suitable growth condition, single crystal ZnO nanorods grow on the well-defined bounded facets of the random shape ZnSe grains using Zn and Se powders without any metal catalyst. The growth direction of ZnSe nanorods on a facet of a ZnSe grain is quite uniform. The synthesis mechanism of the ZnO nanorods on the ZnSe grains is proposed. The effects of the Se powder usage on the ZnO-ZnSe products and the photoluminescence of the products are investigated.
本文首次报道了通过化学气相沉积法在原位合成的ZnSe晶粒上生长的ZnO纳米棒。在合适的生长条件下，使用Zn和Se粉末，无需任何金属催化剂，单晶ZnO纳米棒在形状不规则的ZnSe晶粒的清晰界定的晶面上生长。ZnSe晶粒一个晶面上的ZnO纳米棒的生长方向相当一致。提出了ZnSe晶粒上ZnO纳米棒的合成机理。研究了Se粉用量对ZnO-ZnSe产物及其光致发光的影响。
