摘要： A fluorescent material is disclosed which is excellent in the intensity of color and brightness and suitable for a FED and a precise CRT. The fluorescent material is prepared by co-activating yttrium oxide fluorescent material activated with europium. The means particle size is 10 nm to 100 nm. To prepare the fluorescent material, basic carbonate activated with europium and zinc is used as a precursor which is then baked. The precursor is prepared by a liquid-phase reaction. Specifically, yttrium nitrate, europium nitrate and zinc acetate are allowed to react in a solution together with sodium carbonate. The prepared precursor is baked by a quick heating and cooling As an alternative to this, the precursor is baked together with flux (phosphate of alkali metal).
