| 摘 要： | 采用微乳液法合成黄绿色SrAl2O4：Eu^2＋,Dy^3＋长余辉发光粉体,并且表征其晶体结构、激发光谱、发射光谱和余辉衰减特性.XRD分析表明：所合成的样品为SrAl2O4单斜晶系的晶体结构.激发波长的范围较宽,表明从紫外至可见光均可激发该发光材料.发射光谱主峰位于525 nm.样品在自然光照射后持续发出明亮的黄绿光.最后讨论微乳液体系中表面活性剂用量、激活剂和共激活剂浓度以及灼烧温度对产品发光性能的影响. |
| 关 键 词： | 微乳液法 长余辉发光材料 激活剂 |

| Abstract: | long afterglow luminescent materials SrAl_2O_4:Eu~(2+),Dy~(3+) emitting yellow-green light was synthesized by microemulsion method.The phosphor quartz structure,the excitation spectrum,the emission spectrum and the long decay curve were measured and analyzed.XRD pattern indicates that the phosphor is with monoclinic SrAl_2O_4 crystal structure.The wide range of excitation wavelength indicates that the luminescent material could be excited by the light from ultraviolet ray to visible light.The main emission peak was at 520 nm.The sample excited by ultraviolet visible light can emit bright yellow-green light.The effect of the mass of surfactant,the concentration of radicalness and co-radicalness,sintering temperature on the luminescence properties of the samples were discussed. |
| Keywords: | microemulsion long afterglow luminescent materials radicalness |
