中文摘要：
以P123为介孔模板、以Zn（Ac）2·2H2O和LiOH·H2O为原料制备ZnO前驱体溶胶,对聚苯乙烯（PS）微球模板进行填充,55℃干燥后形成凝胶。经过600℃高温煅烧除去有机模板剂P123和PS,从而得到了具有介孔/大孔分级结构的ZnO材料。采用扫描电子显微镜、傅立叶变换红外光谱仪对分级孔结构ZnO材料进行了表征,并研究了其电致发光性能。结果表明,相同条件下介孔/大孔分级结构ZnO材料的发光强度是介孔ZnO材料的3.3倍。
英文摘要：
ZnO precursors were synthesized by a sol-gel method using pluronic P123 as mesoporous template in this paper.Then filled the polystyrene（PS） template which was self-assembled from PS spheres with the as-prepared ZnO precursors.The gel of polystyrene/inorganic was completed at 55℃ in the drying oven.Hierarchical meso-macroporous ZnO were obtained after the decomposition of the organic template,i.e.PS and P123,by calcining at 600℃ for 10h.The as-prepared samples were characterized by scanning electron microscope（SEM） and Fourier transform infrared spectroscopy（FT-IR）.The electroluminescence results indicate that the EL emission intensity of calcined hierarchical porous ZnO is 3.3 times higher than mesoporous ZnO under the same elecric field intensity.
