Beschreibung
Zusammenfassung:	Disclosed is fluorophosphate glasses for an active device, the fluorophosphate glasses including: a metaphosphate composition including Mg(PO3)2 of about 20 mol % to about 60 mol %; a fluoride composition including BaF2 of about 20 mol % to about 60 mol % and CaF2 of about 0 mol % to about 40 mol %; and dopants including rare earth elements, in which there is an effect of increasing a carrier lifetime at a metastable state energy level that is stimulated-emitted due to an efficient energy transfer phenomenon by composition optimization of dopants (e.g. Er and Yb).
