These phosphors perform well in brightness under the conditions necessary for use in FED's and are of suitable size for use in high definition screens. We also report a green emitting Y2O2S:Tb phosphor that has been prepared by a new method involving homogeneous precipitation of the precursors and a new firing regime. The resulting cathodoluminescent phosphor having submicrometer size particles has a luminous efficiency of 34.6 lm/W at an electron beam accelerating voltage of 5000 V. References R.
