摘要： A systematic investigation on °uorescence spectroscopy of trivalent thulium doped in oxy°uoride glass ceramics containing LaF3 nanocrystals has been carried out in a spectral range from 400 to 900nm under the direct excitation of 1D2 level at a low temperature. Speciˉc optical transitions related to the °uorescence emissions are studied based on experimental measurements in frequency and time domain. Fluorescence emissions from the ions in crystal phase are distinguished from what in glass phase and their spectroscopic properties are explored. The dynamical process shows that the temporal decay of °uorescence emission consists of two parts: a rapid decay from the ions in glass phase and a slower decay from the ions in crystal phase.
