摘要： A process for producing fine phosphor particles having a high crystallinity, having a small amount of aggregated particles and comprising fine particles, thus capable of forming a homogeneous and dense high brightness fluorescent layer when applied to e.g. a cathode ray tube, a fluorescent lamp or PDP, and having a high purity, a uniform chemical composition and excellent emission properties, at a low cost, is provided. A process for producing a phosphor, which comprises heating droplets of a solution containing metal elements constituting the phosphor to carry out pyrolysis to obtain the phosphor, wherein the above heating is carried out in the coexistence of an additive comprising a metal or a metal compound to carry out the pyrolysis at an average crystal growth rate of at least 0.002 &mgr;m3/sec.
