摘要：
We report the observation of upconversion luminescence from Sm2+ ions, which demonstrate that changeable valence lanthanides can served as the ions for optical frequency transformation. Upon the excitation of 980 nm diode laser, the doped Sm2+ ions in the hybrid material of BaFCl0.5Br0.5:1%Sm2+-CaF2:1%Yb3+ emit red upconversion fluorescence peaked at 631, 644, 665, 689, 704, 729 nm from the 5D0,1→7F0,1,2 transitions, respectively. By transient dynamic analysis, we attribute the excitation of Sm2+ ions to the cooperation energy transfer process: two excited Yb3+ ions simultaneously transfer their energy to one Sm2+ ion. © 2017, Science Press.
