摘要:
以氧化铈和碳酸锰为主要原料、氧化铝作分散剂,采用高温固相法在碳还原气氛中首次合成一系列掺杂量为0.01~0.04的Mn掺杂CeO2绿色荧光粉(CeO2:Mn2+),并分析试样的晶体结构、粒径、形貌和发光性能。结果表明:制得的CeO2:Mn2+荧光粉为立方萤石结构,分散剂氧化铝的加入能够避免主晶格CeO2的烧结并促进发光中心的掺杂,氧化铝不会明显改变试样的晶体结构。试样的粒径集中在6~10 μm范围内,颗粒的外形为椭球形和条形。荧光光谱显示,掺杂发光中心Mn2+后,该荧光粉在272 nm紫外光激发下能够发出519 nm高强绿光,其中,CeO2:0.033Mn试样的发光性能最佳。该CeO2:Mn2+绿色荧光粉在显示和照明领域具有良好的应用前景。

Abstract:
A series of Mn-doped CeO2 green phosphors(CeO2:Mn2+) with doping molar fractions of 0.01-0.04 were firstly synthesized by using cerium oxide and manganese carbonate as main materials and alumina as a dispersant via solid-state reaction under carbon condition. The crystal structure,particle size,microstructure and luminescence properties of obtained CeO2:Mn2+ samples were analyzed. It indicated that the CeO2:Mn2+ samples are of pure cubic fluorite-type CeO2 phase. The addition of alumina dispersant can avoid CeO2 host sintering and promote luminescent center doping,while the alumina does not significantly change samples’ crystal structure. The particle sizes are within range of 6-10 μm,and the particle morphology is of ellipsoid and cuboid. Fluorescence spectroscopy results show that,with luminescent center doped with Mn2+, the samples can emit green light with high luminous intensity under 272 nm ultraviolet light exciting,and CeO2:0.033Mn has the best luminescence property among the samples. The CeO2:Mn2+ green phosphors are expected to have good application prospects in the field of display and lighting.
