Zusammenfassung:	To provide a luminescent material that does not cause mixing non-uniformity and self-absorption problems even when fluophor and quantum dot are used together, and that balances both the manufacturing cost and the LED color rendering property and color saturation.SOLUTION: Provided is a luminescent material comprising particles including quantum dots and having an average diameter of 0.06 μm to 30 μm, and fluophor, and in which one of the particles includes a core and a seal layer covering the core, and the quantum dots are disposed between the core and the seal layer.SELECTED DRAWING: None 【課題】蛍光体および量子ドットを一緒に使用しても混合不均一性および自己吸収の問題が生じず、また、製造コストと、ＬＥＤの演色性および彩度を両立させるルミネセント材料を提供する。【解決手段】量子ドットを含みかつ０．０６μｍ〜３０μｍの平均直径を有する粒子および蛍光体を含むルミネセント材料であって、前記粒子の１つはコアおよび前記コアを覆う封止層を含み、前記量子ドットは前記コアと前記封止層との間に配設される。【選択図】なし
