  • Publication number: 20230402559
    Abstract: A fluorescent light-guiding plate is defined by a first surface, a second surface, and edge surfaces, has a platy structure in which quantum dots that absorb at least one or some of components of sunlight and radiate fluorescence are internally dispersed and which is formed of a material different in refractive index from an outside, and allows the fluorescence radiated from the quantum dots to be concentrated onto the edge surfaces and emitted when the sunlight is incident from the first surface. The platy structure is formed by laminating thin resin films in which the quantum dots are dispersed. The thin resin films are formed by spreading out a solution of quantum dots and resin with an organic solvent in which the quantum dots covered with an aggregation inhibitor and a resin material are dispersed, into a thin-film shape, to evaporate the organic solvent and cure the resin material.
