| 摘 要： | 在室温条件下，对Ｅｕ＾３＋：Ｙ２ＳｉＯ５晶体的透射光谱和４５７．９ｎｍＡｒ＾＋激光激发荧光谱进行测量和研究。这些光谱表明，Ｅｕ＾３＋离子在Ｙ２ＳｉＯ５晶体中占据两种最低对称性Ｃ１格位。利用透射光谱和荧光谱对Ｅｕ＾３＋离子的最低激发态＾５Ｄ０的两种格位光谱进行了成功分离。实验发现，在＾５Ｄ０态两种格位谱的谱宽只有０．１ｎｍ左右，其峰间隔约为０．１８ｎｍ。另外，文中还测量了Ｅｕ＾３＋离子的基态＾７ＦＪ

| Abstract: | The transmittance spectra and Fluorescence spectra of Eu3+:Y2SiO5 crystal have been studied at room temperature. Spectral analysis shows that two optical sites with low symmetry were occupied by Eu3+ in this crystal. Spectra of two kinds of C1 sites were resolved at 5D0 level by transmittance spectrum and fluorescence spectrum. There is 0.18 nm space between them, and the spectral linewidths of each site are about 0.1 nm. In addition, some of the level structure of 7FJ(J=0, 1, 2, 3, 4), 5D1, 2 and 5L6 were also observed. |
