摘要： A luminescent converter 200, 220, 240, 260, a phosphor-enhanced light source and a luminaire are provided. The luminescent converter 200 comprises a first organic luminescent material 202, a second organic luminescent material 208 and a third inorganic luminescent material 206. The first organic luminescent material 202, the second organic luminescent material 208 and the inorganic luminescent material 206 absorb a portion of light emitted by the light source and/or absorbs a portion of light emitted by at least one of the other luminescent materials. The first organic luminescent material 202 converts at least a part of the absorbed light into light of a first color distribution. The second organic luminescent material 208 converts at least a part of the absorbed light into light of a second color distribution. The inorganic luminescent material 206 converts at least a part of the absorbed light into a third color distribution to compensate self-absorption of light by at least one of the first organic luminescent material 202 and the second organic luminescent material 208.

摘要： Provided are a method for manufacturing a perovskite nanocrystal particle light-emitter where an organic ligand is substituted, a light-emitter manufactured thereby, and a light emitting device using the same. A method for manufacturing an organic-inorganic-hybrid perovskite nanocrystal particle light-emitter where an organic ligand is substituted may comprise the steps of: preparing a solution including an organic-inorganic-hybrid perovskite nanocrystal particle light-emitter, wherein the organic-inorganic-hybrid perovskite nanocrystal particle light-emitter comprises an organic-inorganic-hybrid perovskite nanocrystal structure and a plurality of first organic ligands surrounding the organic-inorganic-hybrid perovskite nanocrystal structure; and adding, to the solution, a second organic ligand which is shorter than the first organic ligands or includes a phenyl group or a fluorine group, thereby substitutes the first organic ligands with the second organic ligand. Thus, since energy transfer or charge injection into the nanocrystal structure increases through ligand substitution, it is possible to further increase light emitting efficiency and increase durability and stability by means of a hydrophobic ligand.
