QUANTUM DOT MATERIAL, PREPARATION METHOD THEREFOR, AND LIGHT-EMISSION MATERIAL FILM

Resumen de: US20260209600A1

0000 Disclosed are a preparation method for a quantum dot, a preparation method therefor, and a light-emission material film. Controlling a dimension of a luminescent core of a core-shell quantum dot to be 10 nm to 20 nm may improve a blue light absorption rate and a light extraction efficiency during a light conversion process, such that an use amount of a quantum dot material in a device may be reduced, thereby saving a material cost. In addition, since the dimension of the luminescent core is larger than an exciton bohr diameter, a binding effect of excitons in a core is greatly improved, thus reducing a probability of excitons being quenched by interface defect states, and improving water-resistance and oxygen-resistance stability of the quantum dot material.
