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.

Abstract: A light color conversion layer structure includes a pixel separation layer over a substrate. The pixel separation layer includes several separating components. The receiving region over the substrate is defined by adjacent separating components. The light color conversion layer structure also includes a first isolation layer continuously formed over the substrate and on the sidewalls of the separating components surrounding the receiving region. The first isolation layer continuously covers the top surface of the substrate and the sidewalls of the separating components adjacent to the receiving region. The light color conversion layer structure also includes a light color conversion unit within the receiving region and on the first isolation layer. The light color conversion layer structure further includes a second isolation layer on the first isolation layer and the light color conversion unit. The second isolation layer covers the first isolation layer and the light color conversion unit.
