Structure and luminescence properties of a novel broadband green-emitting oxyapatite-type phosphor

Abstract

A single-phase novel green phosphor Sr2Y3(SiO4)2(PO4)O2:Eu2+ with apatite structure was obtained for the first time.

Structural Confinement and Energetic Matching Synergistic Effect toward a High-Energy Transfer Efficiency and a Significant Red Emission Enhancement in a Eu2+,Ln3+ Co-doped Sr9LiMn(PO4)7 Whitlockite Phosphor

“…The whitlockite-type compounds are known to have a high composition flexibility and a great tolerance for ionic substitutions. , Thus, the targeted compounds with the chemical compositions of Sr 9–0.06– x LiMn­(PO 4 ) 7 :0.06Eu 2+ , x Ln 3+ (Ln = La, Gd, Tb, Lu, and Y) were designed and prepared at the same synthesis condition. Figure a depicts the XRD patterns of the representative SLMP:Eu 2+ , Ln 3+ phosphors.…”

The Broadband Emitting and Lattice Occupation Analysis of Eu2+, Eu3+ and Ce3+ co-doped K3YSi2O7 Phosphors

“…[7] Through this method, Sr 2 Y 3 (SiO 4 ) 2 (PO 4 )O:Eu 2+ phosphor can emit green broadband luminescence from 400 to 700 nm. [8] In 2022, Li et al heated zeolite doped with europium in a reducing atmosphere and obtained broadband yellow phosphors with good thermal stability. The phosphor exhibits great thermal stability (80% intensity at 423 K) and a wide emission band (FWHM = 120 nm) when excited by UV light.…”

Governing the crystallographic sites for tuning Eu2+ emission in an apatite oxyfluoride host to be applied for superior white light emitting diodes

“…20,21 To produce multiple coloured emissions including white light, apatite could be the ideal host because of the allowed tuning of various crystal sites either by multiple activator doping mechanisms or via the cationic substitution strategies within these hosts. [22][23][24][25][26] The fluorapatite structure (M 10 (XO 4 ) 6 F 2 ) is known for its abundant nature and high stability. The presence of fluoride ions in this system can generate potential luminescence properties in solid-state lighting due to the presence of a mixed ligand system.…”
