摘要:
为合成结晶度好、分散均匀、性能良好的硅酸锌锰绿色发光材料，以正硅酸乙酯、六水合硝酸锌、四水合醋酸锰为原料， 以尿素作沉淀剂，利用水热均相沉淀法制备了不同二价锰离子掺杂含量的硅酸锌锰绿色荧光粉.采用X射线衍射、扫描电子显微镜、荧光光谱仪对其物相、形貌和发光性能进行了表征，并分析了不同二价锰离子掺杂量对其发光性能的影响.结果表明，在95 ℃水浴24 h， 1 250 ℃煅烧4 h时，可以获得粒径为0.2 μm，分散均匀、形貌良好、单相的硅酸锌锰.发光性能测试表明：二价锰离子最佳掺杂含量为0.08 mol，当掺杂含量超过0.08 mol后光谱会发生浓度猝灭效应.
Abstract:
To make manganese zinc silicate green luminescent material with good crystallinity, uniform dispersion, excellent performance, manganese zinc silicate green phosphor with different doping content of manganous ion was prepared by hydrothermalhomogeneous method using tetraethoxysilane, zinc nitrate hexahydrate, manganous acetate tetrahydrate as raw materials and carbamide as precipitant. The phase structures, morphology and photoluminescence were respectively characterized by Xray diffractometer, scanning electron microscope and fluorescence spectrophotometer, and the influences of different manganous ion doping content on the luminescence performance were also analyzed. Results show that single phase manganese zinc silicate with uniform particle size distribution is obtained when prepared via a hydrothermal aging treatment at 95 ℃ for 24 h then calcinated at 1 250 ℃ for 4 h and its size is about 0.2 μm. Luminous performance tests show that the best content fraction of manganous ion is 0.08 mol, and the concentration quenching effect will happen when the doping content is more than 0.08 mol.
