Abstract Observation of the 532 nm-laser-induced fluorescence spectra of two kinds of Cr:Mg2SiO4 crystalline samples grown in different atomsphere are reported. The experiments were con-ducted at both room temperature and liquid-nitrogen temperature. The fluorescence spectra of the two kinds of samples were different with respect to the polarizing direction of the inducing leser, and two emission bands with different polarized characters and various en-hancement in intensity at low temperatures were also found. In the light of the calculated results by Ms-X$\alpha$ method, the main experimental results are explained.

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.
