Abstract A systematic investigation on fluorescence 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. Specific optical transitions related to the fluorescence 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.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
