| description | To provide a ceramic phosphor having high quantum efficiency without additional processing.SOLUTION: A ceramic phosphor has a base material and a polycrystal formed on at least one surface of the base material. The polycrystal has at least one dendrite. The polycrystal is predominantly composed of an oxide, a fluoride, or an acid fluoride of an alkaline earth metal. The polycrystal has a unit cell of a cubic system. The dendrite has a trunk crystal and a plurality of branch crystals branched from the trunk crystal. A direction in which the branch crystals extend is inclined relative to a direction in which the trunk crystal extends.SELECTED DRAWING: Figure 3
【課題】付加加工なしで高い量子効率を有するセラミックス蛍光体を提供する。【解決手段】セラミックス蛍光体は、基材と前記基材の少なくとも１つの表面に形成された多結晶体とを有し、前記多結晶体は、少なくとも１つの樹状結晶を有し、前記多結晶体は、アルカリ土類金属の酸化物、フッ化物、または酸フッ化物を主成分として含み、前記多結晶体は、立方晶構造の単位格子を有し、前記樹状結晶は、幹結晶と、前記幹結晶から分岐する複数の枝結晶と、を有し、前記枝結晶の延在する方向は、前記幹結晶の延在する方向に対して傾斜している。【選択図】図３ |
