摘要：
The preferential incorporation of Er3+ ions into the PbF 2nanocrystals during the ceraming process of oxyfluoride glass was analyzed using electron energy loss spectroscopy analysis. Concentrations of Er3+ ions were considerably higher in PbF2nanocrystals compared to those in the glass matrix. Changes in lineshapes of absorption spectra from Er3+:4 I15/24 I 13/2transition and lifetimes of the excited-state Er3+ (4 S3/2level) ions also supported the incorporation of Er3+ ions into PbF2nanocrystals. © 2012 The American Ceramic Society.
