摘要

This paper studied the direct upconversion sensitization luminescence of Tm (0.1)Yb(10.9) oxyfluoride vitroceramics pumped by 966 nm diode laser for the first time. We found that there are both strong 477 nm three-photon upconversion fluorescence of (1)G(4)-->(3)H(6) transition and 799. 5 nm two-photon upconversion fluorescence of (3)H(4)-->(3)H(6) transition as well as weak up-conversion fluorescence of (1)D(2)-->(3)H(6), (1)D(2)-->(3)F(4), (1)G(4)-->(3)F(4) and (3)F(3)-->(3)H(6) transitions at 361 nm, 449. 5 nm, 647. 0 nm and (679. 5, 698. 5 nm), respectively.
