Indirect up-conversion sensitization luminescence of Tm(0.1) Yb(10.9): Oxyfluoride vitroceramics induced by 800nm diode laser

This paper reports researches about the indirect up-conversion sensitizatio n luminescence of Tm(0.1)Yb(10.9): oxyfluoride vitroceramics(TmYb:FOV) indu ced 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 lumine scence intensity of TmYb:FOV is much higher than that of TmYb:FOG. It is sh own that this is an effective method to e5nhance up-conversion efficiency. It is found also that the fluorescence branch ratio and the meticulous stru ctures are different between vitroceramics and glass. This disparity comes from cluster effect resulting from micro crystallization of the material.
