| 1 | 单一基质白光荧光粉Ba_3Y_(1-x)(PO_4)_3:xDy^(3+)的合成及其发光特性显示文摘采用高温固相法,合成了Ba3Y1-x(PO4)3:xDy3+荧光粉。X射线衍射(XRD)图谱表明,合成物质为纯相Ba3Y(PO4)3晶体。激发谱和发射谱表明,样品的主发射峰位于486nm(4F9/2→6H15/2)和575nm(4F9/2→6H13/2),为典型的Dy3+特征发射,对应于样品的蓝光和黄光发射,其中以348nm激发时得到的峰值最强。样品的主激发峰有8个,均为Dy3+吸收,分别位于292nm(6H15/2→4D7/2),322nm(6H15/2→6P3/2),348nm(6H15/2→6P7/2),362nm(6H15/2→6P5/2),385nm(6H15/2→4M21/2),424nm(6H15/2→4G11/2),452nm(6H15/2→4I15/2)和473nm(6H15/2→4F9/2)处。研究了Dy3+掺杂浓度对发光性能的影响,在掺杂浓度x=0.08时,出现了浓度猝灭,浓度猝灭机理为电偶极-电偶极相互作用;不同Dy3+掺杂浓度荧光粉发射光的色坐标均在白光区域中。同时,研究了敏化剂Ce3+对Ba3Y(PO4)3:Dy3+材料发光强度的影响。 | 杨志平 王灿 张凤 侯春彩 梁晓双 | 2014 | 光电子.激光2014，25，7： | 5 |
| 2 | Enhancing thermal stability and photoluminescence of red-emitting Sr_(2)Si_(5)N_(8):Eu phosphors via boron doping显示文摘Surface passivation is a common method to improve the resistance of thermal degradation of nitride phosphors.However,such a surface passivation generally needs extra processes and decreases the photoluminescence property of the phosphors.In this work,both the thermal stability and photoluminescence property of a red phosphor Sr_(2)Si_(5)N_(8):Eu are improved through the addition of BN.The influence of B on the crystal structure and the valence state of active ions was analyzed by experimental characterization.First-principles calculations were applied to analyze the formation energy of N vacancies,which influence the resistance of thermal degradation.Finally,combining with experimental characterization and calculations,the enhancing mechanism of thermal stability and photoluminescence by B was studied. | Hailong Yuan Zhifeng Huang Jianwen Zhang Ziqian Yin Xiangyu Lu Fei Chen Qiang Shen | 2021 | Journal of Materials Science & Technology2021，，35： | 1 |
