[求助]
求助中译英，荧光粉发光方面问题
|
|
|
【最理想的荧光材料是激发同一种晶格，能呈现出不同颜色的光发射的荧光材料。例如，Eu2+/Mn2+，Ce3+/Mn2+，Ce3+/Eu2+ 共掺离子在基质中可以呈现出 f-d 或者 d-d电子构型，激发辐射出不同颜色的光。同时由于激活离子之间的多偶极子作用，会发生彼此能带之间的能量转移效应。所以，通过共掺不同的稀土离子，使同一种主晶格的荧光粉，能够发射出绿色-黄色-橙色光，对于提高荧光粉的发光性能，扩大使用范围，具有重要的意义。】 谢谢大家了！  |

The ideal fluorescent material is excited the single lattice which can exhibit different colors of light. For example, Eu2 + / Mn2 +, Ce3 + / Mn2 + of Ce3 + / Eu2 + codoped in the same matrix can exhibit f-d or d-d electronic configuration, following the excitation radiation with different colors emission. Meanwhile, due to the role of a multi-dipole between the active ionic species, the energy transfer will occur between the band and each other. Therefore, by co-doping different rare earth ions, the host lattice of the same kind of the phosphor capable of emitting a green - yellow - orange light, has important significance for improving the luminescent properties of the phosphor, and further expand the scope of applications Hope to be helpful to you |
