摘要： 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\%.
