A quantum dot complex and its manufacturing method, intermediate and applications are provided. The quantum dot complex includes a quantum dot and a plurality of polymeric chain ligands, wherein each of the polymeric chain ligands includes a coordination unit and at least one polymeric chain, and the coordination unit connects the quantum dot with the polymeric chain; and the polymeric chain has a molecular weight distribution of not more than about 1.3. The surface of the quantum dot in the quantum dot complex is bonded to a plurality of polymeric chain ligands by coordination, and the length of the polymeric chain is accurately controllable, so that the viscosity and surface tension of an ink containing the quantum dot complex can be effectively controlled. Moreover, additives can be avoided and a low boiling point solvent can also be used, thereby ensuring the purity of the quantum dots in the ink.

The present invention relates to nanoparticle compositions and, in particular, to composite polymeric nanoparticle compositions. A composite nanoparticle described herein comprises a photoluminescent polymeric component and a photo-thermal polymeric component. The photoluminescent polymeric component and the photo-thermal polymeric component can each comprise a single polymeric species or multiple polymeric species.
