摘要：

Up-conversion processes are studied in (Yb3+, Tb3+) co-doped fluorophosphate glasses. These glasses contain a large concentration of terbium fluoride, up to 36 mol%, and still luminesc. Samples are excited at 980 nm, within the Yb3+ absorption band. For 'low' Yb3+ concentrations, i.e., below 16 mol%, the typical green luminescence of terbium is observed. With increasing Yb3+ concentration, the green luminescence vanishes and a blue emission appears. Both emissions are due to a cooperative effect between two Yb3+ ions.
