Abstract
Official abstract text for this publication.
Disclosed is fluorophosphate glasses for an active device, the fluorophosphate glasses including: a metaphosphate composition including Mg(PO 3 ) 2 of about 20 mol % to about 60 mol %; a fluoride composition including BaF 2 of about 20 mol % to about 60 mol % and CaF 2 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).
First claim
Opening claim text (preview).
What is claimed is: 1. Fluorophosphate glasses for an active device, comprising: a metaphosphate composition including Mg(PO 3 ) 2 of about 20 mol % to about 60 mol %; a fluoride composition including BaF 2 of about 20 mol % to about 60 mol % and CaF 2 of about 0 mol % to about 40 mol %; and dopants including rare earth elements, wherein the dopants are ErF 3 and YbF 3 , the ErF 3 is about 3 mol %, and the YbF 3 is about 3 mol % to about 6 mol %. 2. The fluorophosphate glasses of claim 1 , wherein the Mg(PO 3 ) 2 is about 30 mol %. 3. The fluorophosphate glasses of claim 1 , wherein the CaF 2 is about 20 mol %. 4. The fluorophosphate glasses of claim 2 , wherein the BaF 2 is about 40 mol % to about 60 mol % and the CaF 2 is about 10 mol % to about 30 mol %. 5. The fluorophosphate glasses of claim 3 , wherein the Mg(PO 3 ) 2 is about 30 mol % to about 50 mol % and the BaF 2 is about 30 mol % to about 50 mol %. 6. The fluorophosphate glasses of claim 1 , wherein the YbF 3 is about 4 mol %. 7. The fluorophosphate glasses of claim 6 , wherein the Mg(PO 3 ) 2 is about 30 mol %. 8. The fluorophosphate glasses of claim 6 , wherein the CaF 2 is about 20 mol %. 9. The fluorophosphate glasses of claim 7 , wherein the BaF 2 is about 40 mol % to about 60 mol % and the CaF 2 is about 10 mol % to about 30 mol %. 10. The fluorophosphate glasses of claim 8 , wherein the Mg(PO 3 ) 2 is about 30 mol % to about 50 mol % and the BaF 2 is about 30 mol % to about 50 mol %.
