摘　　要：本文首次研究了Tm(0 1)Yb(10 9)氟氧化物玻璃在 96 6nm半导体激光激发下的直接上转换敏化发光现象。测量发现存在很强的 1G4 → 3 H6的 474nm三光子和较弱的1D2 →3 H6的 36 2nm ,1D2 →3 F4 的 45 2nm ,1G4 → 3 F4 的 6 5 0nm三光子以及3 F3 → 3 H6的 6 81nm二光子上转换发光。This paper studied the direct upconversion sensitization luminescence of Tm(0.1) Yb( 10.9): oxyfluoride glass pumped by 966 rim diode laser. We found that there are strong 474 run three-photon upconversion fluorescence of (1)G(4) --> H-3(6) transition. As well as there are weak 362,452 and 650 rim, three-photon upconversion fluoresence of D-1(2) --> H-3(6), D-1(2) --> F-3(4), (1)G(4) --> F-3(4) and 681 rim two-photon upconversion fluorescence of F-3(3) --> H-3(6) transitions respectively. Their upconversion mechanism has been analyzed and discussed simply.
