Synthesis and optical properties of novel apatite-type NaCa3Bi(PO4)3F:Dy3+yellow-emitting fluorophosphate phosphors for white LEDs
文献摘要：
In this study,novel yellow-emitting fluorophosphate NaCa3Bi(PO4)3F phosphors doped with different concentrations of Dy3十 ions were first obtained via high-temperature solid-state reaction.The crystal structure,phase purity,particle morphology,photoluminescence(PL)properties,thermal stability,and luminescence decay curves of the resulting phosphors were then characterized in detail.Under the excitation of 349 nm,the three dominant peaks of the NaCa3Bi(PO4)3F:Dy3+are centered at 480 nm(4F9/2-6H15/2),577 nm(4F9/2-6H13/2),and 662 nm(4F9/2-6H11/2).The optimal doping concentration of Dy3+ions in the NaCa3Bi(PO4)3F:xDy3+phosphors is x=5 mol％.The phosphors show excellent thermal stability with high activation energy(Ea=0.32 eV).Eventually,the synthesized white light-emitting diode(w-LED)demonstrates the Commission International de L'Eclairage(CIE)chroma-ticity coordinates of(0.341,0.334),a good correlated color temperature(CCT)of 5083 K,and a high color rendering index(Ra)of 92.Revealing its potential as yellow-emitting phosphors,the feasibility of the fabricated apatite-type NaCa3Bi(PO4)3F:Dy3+fluorophosphate phosphors was confirmed for w-LEDs.
