  • Publication number: 20190301709
    Abstract: The present invention discloses a light conversion material with light reflective structure, comprises: a transparent substrate, a plurality of first light conversion films and second light conversion films. Particularly, the second light conversion film is disposed between two of the first light conversion films, and has a refractive index greater than that of the first light conversion film. By such design, when a short-wavelength light is incident on the first light conversion films and the second light conversion films, parts of the short-wavelength light have a reflected light forming at the junction between the two light conversion films, and the reflected light would bounce back to the first light conversion film and/or the second light conversion film, thereby those unconverted short-wavelength light being prevented from directly passing the light conversion material. Briefly speaking, this light conversion material exhibits an outstanding performance on short-wavelength light recycling.

  • Publication number: 20190293842
    Abstract: Light scattering particles made of TiO2, BaSO4, SiO2, or Al2O3 have been used in a QD layer of a QD-LED for enhancing luminous intensity. However, the light scatters are found to decline the light conversion efficiency of the QD layer. In view of that, the present invention particularly discloses a light conversion material with high conversion efficiency for use in the QD-LED. The light conversion material mainly comprises a polymer matrix, a plurality of 3D photonic crystals dispersed in the polymer matrix, and a plurality of quantum dots dispersed in the polymer matrix, wherein each of the plurality of 3D photonic crystals is formed by applying a self-assembly process to a plurality of polymer beads. Moreover, a variety of experimental data have proved that, this light conversion material indeed exhibits outstanding photoluminescence intensity and light conversion efficiency both superior than that of the conventionally-used QD layer.
