A light-emitting device (52) suitable for a flat-panel cathode-ray tube
display contains a light-emissive region (66) formed over a plate (64).
The light-emissive region contains a plurality of light-emissive particles (72).
Part of the outer surface of each of a group of the light-emissive particles is
conformally covered with a group of intensity-enhancement coatings (82 and 84).
