摘要 | Nanocrystalline zirconia co-doped with Yb3+ and Tm3+ ions was prepared by co-precipitation. Up-conversion luminescence of the samples doped with different Tm3+ concentrations was investigated under a 980 nm LD excitation. When chi = 0. 2 and 0. 4, the luminescences of the two samples were mostly the same: strong blue up-conversion peaked at 474 nm and very weak red up-conversion were observed, corresponding to the transitions of (1) G(4) --> (3) H-6 and (1) G(4) --> (3) F-4 respectively. However, there was no luminescence of x = 1. Blue up-conversion luminescence of 0. 2 mol % Tm3+-ions-doped nanocrystalline zirconia under different annealing temperatures was investigated. Blue up-conversion emission grew stronger with annealing temperature increasing. With pumping current increasing, blue up-conversion emission grew stronger too. By studying the sources of blue up-conversion, we concluded that it was three-photon process. |
