| Abstract: | This paper reports researches about the indirect up-conversion sensitization luminescence of Tm(0.1)Yb(10.9): oxyfluoride vitroceramics(TmYb:FOV) induced by 800nm diode laser. From the initial comparison research of indirect up-conversion sensitization luminescence between TmYb:FOV and Tm(0.1)Yb(10.9): oxyfluoride glass (TmYb:FOG), it is found that the up-conversion luminescence intensity of TmYb:FOV is much higher than that of TmYb:FOG. It is shown that this is an effective method to e5nhance up-conversion efficiency. It is found also that the fluorescence branch ratio and the meticulous structures are different between vitroceramics and glass. This disparity comes from cluster effect resulting from micro crystallization of the material. |
