| 摘 要： | 本文在CF4气氛中以提拉法成功地生长出高质量的掺入Tm3+、Ce3+的LiLuF4和LiYF4晶体,对比了Ar和CF4气氛中生长的LiYF4晶体的红外光谱特性,讨论了CF4气氛对LiM(M=Y,Lu)F4晶体生长的影响.同时测试了Tm3+、Ce3+在LiLuF4和LiYF4晶体中的有效分凝系数,从离子半径和晶胞畸变的角度,讨论了Tm3+、Ce3+在LiLuF4和LiYF4晶体中有效分凝系数差别的产生原因.

| Abstract: | Tm3+,Ce3+ doped LiLuF4 and LiYF4 crystals with high quality were successfully grown under CF4 atmosphere by Czochlalski method.IR spectra were measured and compared with those of the crystals grown under Ar atmosphere.The influence of CF4 atmosphere on crystal growth and contamination in crystals were discussed.The effective distribution coefficients of Tm3+,Ce3+ in LiLuF4 and LiYF4 crystals were measured and reported in this paper.The originating reason of difference in the effective distribution coefficie... |
