光物理是未来信息社会的支柱基础与技术之一，频率上转换现象的研究则是光物理学科的热点前沿课题． Ｅｒ３＋离子是发光现象最丰富的稀土离子之一，而Ｙｂ３＋离子由于其能级的特殊性，在上转换敏化中有特殊的价值，但同时由Ｙｂ３＋导致的交叉能量传递也是不可回避的问题，因
Photophysics is one of the pillars and technologies of information society in the future. The research on the phenomenon of frequency conversion is a hot topic in photophysics. Er3 + ion is one of the rare earth ions with the most luminescence phenomenon. However, Yb3 + ion has special value in upconversion and sensitization because of its energy level. However, the cross energy transfer caused by Yb3 + is also unavoidable. because
