title: Yellow-emitting NaCaPO4:Mn2+ phosphor for field emission displays.
abstract: Yellow-emitting NaCaPO(4):Mn(2+) phosphors were prepared by the Pechini sol-gel process. Under low voltage electron beam excitation, the NaCaPO(4):Mn(2+) phosphor screen shows bright yellow emission (centering at 560 nm due to the (4)T(1)→(6)A(1) transition of Mn(2+)) with the CIE color coordinate (0.428, 0.552), which has a higher color purity than commercial yellow-emitting FED phosphor (Zn, CdS):Ag(+). The color range and chromaticity saturation may be greatly enhanced when the yellow-emitting NaCaPO(4):Mn(2+) is added as an additional phosphor of the typical tricolor FEDs phosphors, which make them have potential to improve the display quality of full-color FEDs.
