Ce:LiM(M=Ca,Sr)A1F<sub>6</sub>晶体生长与性能研究

报道了在CF4气氛中生长的掺Ce3+的LiM(M=Ca,Sr)A1F6晶体和掺Ce3+的LiSr0.8 Ca0.2AlF6混晶,以及Ce3+在这些晶体中的紫外吸收光谱及有效分凝系数.Ce3+:LiSr0.8Ca0.2AlF6在240～280 nm波长范围内有连续展宽的吸收带,它的有效分凝系数为0.037.Ce3+的吸收带展宽是由于Ce3+替代晶体中二价离子位引起的,表明Ce3+在Colquiriite结构的晶体中替代的是二价位.

Abstract

Crystal growth of Ce 3+ doped LiM(M=Ca, Sr)AlF 6 mixed crystal were successfully carried out in CF 4 atmosphere. The UV absorption spectra and the effective segregation coefficients of Ce 3+ ions in these crystals were measured and reported. Ce∶LiSr 0.8Ca 0.2AlF 6 crystal shows a broaden absorption band in the wavelength range of 240～280 nm, and the effective segregation coefficient of Ce 3+ ions in the mixed crystals is 0.037. It is believed that the broadening of the absorption band in the Ce∶LiSr 0.8Ca 0.2AlF 6 crystal was caused by substitution of Ce 3+ ions for divalent ions in the Colquiriite structure crystals.
