| 摘 要： | 用稀土复合溶胶雾化-热解方法制备了Ba3MgSi2O8:Eu2 ,Mn2 荧光材料,在近紫外光激发下,可同时发射红、绿和蓝三光进而合成白光.用微结构参数与发射波长的半定量关系,验证了505 nm绿光发射来自于Ba3MgSi2O8主基质相中伴生的微量Ba2SiO4相;基于Mn2的激发光谱和Eu2 的发射光谱的重叠关系,红光来源于Eu2 的蓝光发光中心的能量传递,分析了Eu2 和Mn2 之间的能量传递机理.

| Abstract: | A phosphor,Ba3MgSi2O8:Eu2 ,Mn2 is synthsizerd via rare-earth composite sol spray-pyrolysis route.This phosphor has three emission bands of red,green and blue,which can be combined to white light under near-UV light irradiation.A semi-quantitative formula between microstructure parameter and lowest energy edge,verified that 505 nm-peaked green emission originate from a coexisting Ba2SiO4 phase in dominant Ba3MgSi2O8 host;In terms of overlap relationship between excitation band of Mn2 and emission band of Eu2 ,red emission ascribe to some energy transfer from blue luminescent center of Eu2 ,and the mechanisms of energy transfer between Eu-Mn are detailed. |
