摘　　要：建立溶液配位反应-沉淀反应多重平衡合成前驱体的方法,成功合成了基于海洋硅藻硅质壳三维多孔状结构的氧化锌纳米材料,并使用扫描电子显微镜(FESEM)、透射电子显微镜及能谱仪(TEM-EDS)、傅里叶变换红外光谱仪(FT-IR)对其进行了表征。同时,对硅藻硅质壳结构氧化锌纳米材料进行了发光性能的分析和比较研究。结果表明硅藻硅质壳模板合成后的氧化锌材料在蓝绿光可见区(400～550 nm)有光致发光效应,与模板合成前相比光致发光性能上提高了14.55%。Herein, a multi-equilibrium involving complex ions and slightly soluble ionic compounds to fabricate 3-D zinc oxide nanoperous phetoluminescence structures by templating diatom frustules is demonstrated for the first time. FESEM, TEM in combination with EDS, FT--IR spectra analysis ore used to detect structures and elements. Meanwhile, Photoluminescence properties of the silica-- based ZnO replica by diatom frustules are discussed compared with ZnO particles in the same approach without frustules. ZnO photalumineseence signals in blue--green visible part of the spectra at wavelength ranging from 400 nm to 550 nm have been improved 14.55% after templating diatom frustules.
