| Abstract: | 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. |
