Summary:The invention discloses a preparation method of a fluorescent material. The preparation method comprises the following steps: according to the stoichiometric ratios of all elements in a chemical formula of Ca<2-2x>Eu Mo2O9, a compound containing Ca2+, a compound containing Mo6+, and a compound containing Eu3+ are weighed, ground and evenly mixed, the mixture is pre-sintered under an air atmosphere, naturally cooled, and then ground and evenly mixed, wherein x is the mole percent doped with the Eu3+ and is larger than or equal to 0.001 and smaller than 1.0; the mixture is calcined in the airatmosphere, the calcining temperature is 800 to -900 DEG C, and the calcining time is 6 to -15 hours; and the mixture is cooled to the room temperature and evenly ground, and then the powdery fluorescent material is obtained. Raw materials adopted by a preparation process are easy to obtain, the operating steps are simple, and repeatability is good; the sintering temperature in the preparation process is low, and the requir
