| 英文摘要 | 3at%Yb:Ca1-xRxF2+x(R=La, Gd; x=0, 0.01, 0.03, 0.06, 0.09) crystals were grown by a vertical Bridgman method. X-ray diffraction (XRD), Raman spectra, absorption spectra, fluorescence spectra and fluorescence lifetime were used to characterize the crystals. Effects of regulating ion La3+and Gd3+on lattice constants, Raman spectra and properties of Yb:CaF2crystals were investigated. Moreover, the relationship between structure and spectral property of Yb3+ion was analyzed and discussed. The results show that lattice constant and Raman FWHM gradually increase with the increase of La3+or Gd3+ion doping concentration, demonstrat that lattice expands and lattice vibration modes increases, respectively. Among 3at%Yb:Ca1-xLaxF2+xcrystals, the crystal doped with 6at% La3+has the largest absorption cross section (0.71×10-20cm2) and the largest fluorescence intensity. Moreover, the crystal doped with 3at% Gd3+has the largest fluorescence intensity. Increasing Gd3+content up to 6at%, the crystal has the largest absorption cross section (0.64×10-20cm2). These cooping crystals have better spectral parameters than 3at%Yb:CaF2crystals. Based on the above results, structure of Yb3+ion may be changed and the crystalline spectral properties may be optimized partly through the regulation of La3+or Gd3+ions' concentration. © 2017, Science Press.
