Process for producing fluorescent material

---

Abstract

---

The present invention relates to a process for producing a composite-fluoride fluorescent material represented by the general formula A₂MF₆:Mn⁴⁺ (wherein A is at least one alkali metal element including K; M is one or more metallic elements including at least Si or Ge and selected from among Si, Ge, Sn, Ti, Zr, and Hf; F is fluorine; and Mn is manganese). With the production process, it is possible to obtain a fluorescent material which is high in absorptance, internal quantum efficiency, and external quantum efficiency and has excellent optical properties.
