Abstract The absorption and emission spectra of the YVO$_4$ single crystal co-doped with 1 at.% Nd$^{3+}$ and 1 at.% Yb$^{3+}$ are investigated. The efficient Nd$^{3+}$ $\rightarrow$ Yb$^{3+}$ energy transfer and the back transfer (Yb$^{3+}\rightarrow$ Nd$^{3+}$) are observed at room temperature. The fluorescence lifetime of the $^4$F$_{3/2}$ level of Nd$^{3+}$ in Nd,Yb:YVO$_4$ is measured under 808 nm laser light excitation. The efficiency of Nd$^{3+}\rightarrow$ Yb$^{3+}$ energy transfer in YVO$_4$ is determined to be about 34%.

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.
