摘要： The up-conversion luminescent property of the oxyfluoride glass ceramics 30SiO_{2}\cdot15Al_{2}O_{3}\cdot (50--x)PbF_{2}\cdot xCdF_{2} doped with 4ErF_{3}\cdot1YbF_{3} has been investigated. Up-conversion luminescent intensity of Er^{3+} ions increased obviously after heat-treatment due to co-doping with CdF_{2}. The structure model of nanocrystals Pb_{x}Cd_{1-x}F_{2} was determined and the effect of CdF_{2} in oxyfluoride glass ceramics was explained by the analysis of x-ray diffraction data. Different nucleation temperatures of samples with different compositions were obtained by differential thermal analysis curves and the results showed the growth process of different nanocrystals in glass ceramics.

Abstract: The up-conversion luminescent property of the oxyfluoride glass ceramics 30SiO2$\cdot$15Al2O3$\cdot$ (50--x)PbF2$\cdot$ xCdF2 doped with 4ErF3$\cdot$1YbF3 has been investigated. Up-conversion luminescent intensity of Er3+ ions increased obviously after heat-treatment due to co-doping with CdF2. The structure model of nanocrystals PbxCd1-xF2 was determined and the effect of CdF2 in oxyfluoride glass ceramics was explained by the analysis of x-ray diffraction data. Different nucleation temperatures of samples with different compositions were obtained by differential thermal analysis curves and the results showed the growth process of different nanocrystals in glass ceramics.
