Description

technical field [0001] The invention belongs to the technical field of electroluminescence diode display, and in particular relates to an inorganic nanometer material printing ink and a preparation method and application thereof. Background technique [0002] Quantum dots (quantum dots, QDs), also known as nanocrystals, are nanoparticles composed of semiconductor materials (usually IIB-VIA or IIIA-VA elements). Quantum dots are zero-dimensional (zero-dimensional) nano-semiconductor materials, and the size of the three dimensions is not larger than twice the exciton Bohr radius of the corresponding semiconductor material. The performance of quantum dots is generally affected by the quantum confinement effect ( quantum confinement effect), surface effects and doping effects. Quantum dots are generally spherical or quasi-spherical, and their particle size is stable between 2 and 20nm. Since electrons and holes are quantum-confined, the continuous energy band structure becomes ...
