    • A mixed melt, which contains urea and/or a urea derivative and contains a metal compound, is prepared. The mixed melt is solidified, by heating, whereby the urea and/or urea derivative is decomposed, 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.
    • 制备含有尿素和/或脲衍生物并含有金属化合物的混合熔体。 混合的熔体通过加热固化,由此使尿素和/或尿素衍生物分解,由此制备前体。 将如此制备的前体研磨,然后将如此研磨的前体烧制。 金属化合物的金属可以是选自Al,B,Ba,Be,Bi,Ca,Cd,Cs,Ga,Ge,Hf,In,K,Li,Mg中的至少一种金属 ,Mo,Na,Nb,P,Rb,Si,Sn,Sr,Ta,Ti,V,W,Zr和稀土金属。 因此,以低成本且有效地生产不含杂质并且具有均匀粒度的细粉末状磷光体。
