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 1G4 --> 3H6 transition and 799.5 nm two-photon upconversion fluorescence of 3H4 --> 3H6 transition as well as weak upconversion fluorescence of 1D2 --> 3H6, 1Dz --> 3F4,1G4 --> 3F4 and 3F3 --> 3H6 transitions at 361 nm, 449.5 nm, 647.0 nm and (679.5, 698.5 nm), respectively.
本文首次研究了966nm二极管激光器泵浦的Tm(0.1)Yb(10.9)氟氧化物微晶玻璃的直接上转换敏化发光。我们发现,既有1G4→3H6跃迁的强477nm三光子上转换荧光和3H4→3H6跃迁的799.5nm双光子上转换荧光,也分别有1D2→3H6、1Dz→3F4、1G4→3F4和3F3→3H6跃迁在361nm、449.5nm、647.0nm和(679.5,698.5nm)处的弱上转换荧光。
