以半导体光催化剂ZnO为研究对象,通过热分解前驱体(十二烷基苯磺酸锌)制备ZnO组装体.采用FT-IR、XRD和SEM对试样的结构进行分析,并用PL对其光致发光性能进行了研究.结果表明,在焙烧温度为950℃,焙烧时间为8 h时,可以得到近似有序结构的纯相的具有六角纤锌矿结构的纳米ZnO.其紫外近带边发生和深能级复合的光致发光谱强度比为0.4.
ZnO composites were prepared by thermal decomposition of precursor ZnO (zinc dodecylbenzenesulfonate). The structure of the samples was analyzed by FT-IR, XRD and SEM. The PL The results show that the nano-ZnO with hexagonal wurtzite structure can be obtained when the calcination temperature is 950 ℃ and the calcination time is 8 h. And the deep level of composite photoluminescence intensity ratio of 0.4.
