Abstract
The strong 479.1Â nm blue cooperative upconversion luminescence of ytterbium Yb3+ ion doped oxyfluoride nanophase vitroceramics (Yb:FOV) is studied in this article. It is found that the 479.1Â nm blue cooperative upconversion luminescence strength of Yb(5):FOV is 230 times greater than that of fluoride glass Yb(3):ZBLAN. The large enhancement on cooperative upconversion blue luminescence of this article results from the comprehensive improvement on the aspects of better coupled chance of the Yb3+-Yb3+ cluster, less cross-relaxation, better concentration contribution of Yb3+ activator, non-saturation, and better upconversion luminescence efficiency.
