PROBLEM TO BE SOLVED: To provide a wavelength conversion material and its use.SOLUTION: A light-emitting diode package structure 318 includes a light-emitting diode chip 302, a base 320, a wavelength conversion layer 324 and a reflection wall 326. The wavelength conversion layer 324 is on the light-emitting side of the light-emitting diode chip 302. A wavelength conversion material for use in the wavelength conversion layer 324 contains total inorganic perovskite quantum dots having a formula CsPb(ClBrI), where 0≤a≤1, 0≤b≤1.SELECTED DRAWING: Figure 3 【課題】波長変換材料およびその用途を提供する。【解決手段】発光ダイオードパッケージ構造体３１８は、発光ダイオードチップ３０２、基部３２０、波長変換層３２４および反射壁３２６を含む。波長変換層３２４は、発光ダイオードチップ３０２の発光側にある。波長変換層３２４に用いる波長変換材料は、ＣｓＰｂ（ＣｌaＢｒ1-a-bＩb）3の化学式を有する全無機ペロブスカイト量子ドットを含み、式中、０≦ａ≦１、０≦ｂ≦１である。【選択図】図３
