The red phosphor material comprises Eu, europium from Eu compound, europium chloride as an activator and CdMoO4, cadmium molybdenum oxide as a matrix. The matrix composition is prepared by mixed hydrolytic reaction with cadmium compound and molybdenum compound. The amount of Eu is 0.1-0.5% against the matric compound. The red phosphor with this mixture is prepared by (a) heating at 600-800 deg.C for 60-90 min. in the oxidation atmosphere, (b) atomizing the heated body to the size of 10 micrometer, (c) heating at 1,000-1,200 deg.C for 60-90 min. for crystallization of the material, (d) atomizing the heated material to the size of 3 micrometer, (c) heating the material at 400-600 deg.C for 60-120 min.
