Abstract Based on the analysis of group-chain scheme, the crystal-field-level fitting of Nd3+: LiYF4 has been carried out, in which the Nd3+ inos occupy positions with site symmetry S4. The RMS deviation of energy-level fitting is 12.8cm-1. Using the obtained wave functions, g-factors of the fround state are calculated,which are g∥=2.067 and g⊥=2.631, in good agreement with the experimental values(g∥=1.978 and g⊥=2.554). The method proposed turns out to be effective in the study of spectral properties of localized centres in laser crystals.

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.
