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.

摘要

通过佩琴尼溶胶-凝胶法制备了发黄光的NaCaPO(4):Mn(2+) 荧光粉。在低电压电子束激发下，NaCaPO(4):Mn(2+) 荧光粉屏幕呈现出明亮的黄光发射（由于Mn(2+) 的 (4)T(1)→(6)A(1) 跃迁，发射峰位于560 nm），其CIE色坐标为(0.428, 0.552)，比商用发黄光的场发射显示器荧光粉(Zn, CdS):Ag(+) 具有更高的色纯度。当将发黄光的NaCaPO(4):Mn(2+) 作为典型三色场发射显示器荧光粉的附加荧光粉添加时，颜色范围和色度饱和度可能会大大提高，这使其有潜力改善全色场发射显示器的显示质量。
