| 摘要: 氧化锌不同形貌的合成与控制可以通过一个简单的溶剂热反应来实现，其中乙醇作溶剂，酒石酸做添加剂。通过控制酒石酸的加入量，可以有效地控制ZnO的形貌、尺寸以及到更复杂结构的转变。同时提出了不同形貌ZnO可能的生长机制，并利用FTIR谱进一步证实了酒石酸对ZnO生长的影响。另外，由光致发光光谱可以看出，不同的ZnO形貌，发光性能会有所不同，总体上说，所得ZnO的发光区域主要集中在紫光波段和橙光波段。 |

| Abstract: A facile solvothermal synthesis of ZnO architectures has been developed using ethanol as solvent and tartaric acid as the additive. The variational quantities of tartaric acid controlled the ZnO morphology and shape as well as the self-assembly of ZnO crystals into complex architectures. Possible growth mechanisms of obtained ZnO with different morphologies were proposed. The influence of tartaric acid to ZnO growth was further indicated by FTIR spectra. In addition, the photoluminescence (PL) properties of these ZnO samples were investigated at room temperature, which indicated that the ZnO morphology could influence its optical property. On the whole, the fluorescence was violet emission and orange emission primarily. |
