摘要： This paper studies the upconversion luminescence phenomenon of the Ho,Yb co-doped oxyfluoride vitroceramics. There is one group of strong upconversion luminescence lines positioned at 536.5nm, 18639cm-1; 540.5nm, 18501cm-1; 544.0nm, 18399cm-1, which is easily identified as the transitions of 5S2→5I8. There are other splendid upconversion luminescence lines, which are 5S2→5I7,5F5→5I8,5G6→5I8, (5G3G)5 →5I8,(3F3H5G)4→5I7,5G4→5I8 and (5G3H)5→5I8. It is also found that an interesting kind of upconversion cooperative radiation fluorescence comes from a kind of coupling state of clusters consisting of two Yb3+ ions.
