The results of the integral absorption cross-section analysis demonstrated that the partition fraction of Er^3+ in LaF3 nanocrystals increases with prolonging of heating time, The anomalous phenomena of Er^3+ emissions in the up-and the down-conversion fluorescence spectra are well explained based on the calculated results.展开更多

文摘The distribution characteristics of Er^3+ ions doped in the oxyfluoride glass ceramics containing LaF3 nanocrystals heat-treated at 650 ℃ for different durations were investigated.
