Abstract: A luminescence conversion material is provided. The luminescence conversion material includes: a hybrid luminescence conversion particle, a first cladding material covering the hybrid luminescence conversion particle, and a second cladding material formed on the first cladding material and covering the first cladding material. The hybrid luminescence conversion particle includes a matrix and a plurality of quantum dots uniformly dispersed in the matrix. The first cladding material includes silicon oxide. The ratio α (absorbance ratio α: A939/A1000-1150) of the absorbance at 939 cm−1 (A939) to the absorbance peak at 1000-1150 cm−1 (A1000-1150) in a FTIR spectrum of the first cladding material is less than or equal to 0.8.
