| 中文摘要 | This paper researches the direct up-conversion sensitization luminescence of ErYb codoped oxyfluoride glassceramics (ErYb:FOV) excited by CW 966 nm-diode laser. It is found that the upconversion mechanism of direct upconversion sensitization luminescence of YbEr:FOV sample is mainly the energy transfer between Er3+ and Yb3+ ion but not the step-by-step absorption of single Er3+ ion. This oxyfluoride vitroceramics is forming PbxCd1-xF2 fluoride micro-crystallines. And the rare earth ions tend to concentrate in the micro-crystalline, in which there is an intense cluster effect. So upconversion luminescence is very strong. On the other hand, the log-log variation of up-conversion luminescence intensity with laser power emerges a kind of "typical saturation phenomenon", in which F-P curve is bended gradually resulting from population exhausting in ground state. We also find a new kind of up-conversion cooperative radiation fluorescence originating from a kind of Couple State of cluster consisting of two Yb3+ ions in this ErYb:FOV. |
