PROBLEM TO BE SOLVED: To provide a method for producing fluorescent particles. SOLUTION: The method for producing fluorescent particle is a process of irradiating a target 7 in a solvent 5 with a laser beam 2. Therein, the target is preferably made of Sr<SB>2</SB>MgSi<SB>2</SB>O<SB>7</SB>:Er, Dy, SrAl<SB>2</SB>O<SB>4</SB>:Eu, Dy, SrAl<SB>2</SB>O<SB>4</SB>:Eu, Sr<SB>4</SB>Al<SB>14</SB>O<SB>25</SB>:Eu, Dy, Ca<SB>2</SB>Al<SB>2</SB>SiO<SB>7</SB>:Ce, CaAl<SB>2</SB>O<SB>4</SB>:Eu, Nd, Lu<SB>2</SB>SiO<SB>5</SB>:Ce, ZnS:Cu, CaSrS:Bi, CaS:Eu, Tm. Further, the liquid is preferably a polar solvent such as pure water, methanol, ethanol and propanol and a nonpolar solvent such as hexane and benzene. Furthermore, a substance to be added to the liquid is preferably an anionic surfactant such as sodium dodecyl sulfate, a cationic surfactant such as cetyltrimethylammonium bromide, an ampholytic surfactant such as alkylcarboxybetaine and a nonionic surfactant such as polyethylene glycol and polyvinylpyrrolidone.
