| 摘 要： | The absorption and emission spectra of the YVO4 single crystal co-doped with 1 at.% Nd^3＋ and 1 at.% Yb^3＋ are investigated. The efficient Nd^3＋ → Yb^3＋ energy transfer and the back transfer （Yb^3＋ → Nd^3＋） are observed at room temperature. The fluorescence lifetime of the 4F3/2 level of Nd^3＋ in Nd,Yb：YVO4 is measured under 808 nm laser light excitation. The efficiency of Nd^3＋ → Yb^3＋ energy transfer in YVO4 is determined to be about 34%.

| 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\%. |
