| 摘 要： | The spectroscopic characterization and fluorescence dynamics of Yb^3＋：LiLa（WO4）2 crystal are investigated. The Yb^3＋：LiLa（W04）2 crystal exhibits a broad absorption and emission spectral bands, large absorption and emission cross sections, and moderate fluorescence lifetime. Blue light emission around 480 nm is observed at 10 K and is demonstrated through cooperative upconversion from the deexcitation of excited Yb^3＋-Yb^3＋ pairs.
