Color Point Tuning by Partial Ba2+ Substitution of Ca 2+ in (Ca1-xBax)3(PO 4)2 Phosphor for White Light Emitting Diodes
A potential phosphor (Ca1-xBax)3(PO 4)2:Eu2+ was synthesized by a solid-state reaction. X-ray diffraction (XRD) analysis confirmed the formation of (Ca 1-xBax)3(PO4)2 crystal phase. With the Ba2+ content increasing, the bandgap of (Ca 1-xBax)3(PO4)2 increases from 5.5 to 5.9 eV, and the crystal fiel...
