A method of producing an electroluminescence phosphor, which contains the steps of: mixing a phosphor matrix, a flux, an activator, and a particle diameter-controlling additive that does not enter into a crystal lattice of the phosphor matrix, to give a mixture; and baking the mixture, to produce the electroluminescence phosphor, the method containing the step of: adding an acidic or alkaline solution, to remove the particle diameter-controlling additive from the phosphor; an electroluminescence phosphor, which is produced by the method; and an electroluminescence device, which contains the electroluminescence phosphor. |
