摘要： Quantum dots that are cadmium-free and/or stoichiometrically tuned are disclosed, as are methods of making them. Inclusion of the quantum dots and others in a stabilizing polymer matrix is also disclosed. The polymers are chosen for their strong binding affinity to the outer layers of the quantum dots such that the bond dissociation energy between the polymer material and the quantum dot is greater than the energy required to reach the melt temperature of the cross-linked polymer.

摘要： Provided are a perovskite optoelectronic device containing an exciton buffer layer, and a method for manufacturing the same. The optoelectronic device of the present inventive concept comprises: an exciton buffer layer in which a first electrode, a conductive layer disposed on the first electrode and comprising a conductive material, and a surface buffer layer containing fluorine-based material having lower surface energy than the conductive material are sequentially deposited; a photoactive layer disposed on the exciton buffer layer and containing a perovskite photoactive layer; and a second electrode disposed on the photoactive layer. Accordingly, a perovskite is formed with a combined FCC and BSS crystal structure in a nanoparticle photoactive layer. The present inventive concept can also form a lamellar or layered structure in which an organic plane and an inorganic plane are alternatively deposited; and an exciton can be bound by the inorganic plane, thereby being capable of expressing high color purity.

摘要： A semiconductor quantum dot is provided with a non-metallic substrate, and has a particle size ranged from 0.3 to 100 nm. A method of carrying out a chemical reaction or a photoluminescence reaction by using the semiconductor quantum dot is also provided. A redox reaction of a target sample is carried out, an active substance is generated, or an electron-hole pair is produced from the semiconductor quantum dot by providing the semiconductor quantum dot with a predetermined energy. Photons are released by the combination of the electron-hole pair so as to perform the photoluminescence reaction.
