| 简介 |
A mixed melt, which contains urea and/or a urea derivative and contains a metal compound, is prepared. A temperature of the mixed melt is raised, and the mixed melt is solidified, a precursor being thereby prepared. The thus prepared precursor is ground, and then the thus ground precursor is fired. The metal of the metal compound may be at least one kind of a metal selected from the group consisting of Al, B, Ba, Be, Bi, Ca, Cd, Cs, Ga, Ge, Hf, In, K, Li, Mg, Mo, Na, Nb, P, Rb, Si, Sn, Sr, Ta, Ti, V, W, Zr, and rare earth metals. A finely powdered phosphor free from inclusion of impurities and having uniform particle size is thus produced at a low cost and efficiently. |
