摘　　要：以乙醇/水为介质,利用ZnSO4与碱的反应制备片状前躯体,然后在300℃下煅烧2 h获得ZnO纳米片。采用XRD、TEM、SEM、光致发光谱等手段对产物进行分析和表征,研究了锌源、碱源和煅烧温度对产物形貌的影响。结果表明:采用该法可获得纤锌矿结构ZnO纳米片,其大小100~400 nm,厚度5~10 nm,具有良好的光致发光性能。The precursor was first made by the reaction of zinc sulfate and alkali using ethanol/H2O as medium.Then ZnO nanosheet was obtained by the thermal decomposition of the precursor at 300 ℃ for 2 h.The ZnO nanosheet was characterized by means of XRD,TEM,SEM and PL spectrum.The effect of the kind of zincate,alkali and calcination temperature on morphology were discussed.The results showed that the obtained ZnO nanosheet had good photoluminescence properties.The diameter and thickness of ZnO nanosheet are 100~400 nm and 5~10 nm,respectively.
