QUANTUM DOT STRUCTURE AND MANUFACTURING METHOD THEREFOR, OPTICAL FILM AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE

摘要

A quantum dot structure and a manufacturing method therefor, an optical film and a manufacturing method therefor, and a display device. The quantum dot structure (100) comprises a quantum dot (110) comprising a quantum dot body (112) and a quantum dot surface layer (114), and an oxide layer (120) on the surface of the quantum dot (110) and partially covering the surface of the quantum dot (110). The quantum dot surface layer (114) comprises anions (116), and the oxide layer (120) combines with the anions (116) by means of coordination bonds. The quantum dot structure (100) can improve the optical stability and chemical stability of quantum dots, and can maintain the initial fluorescence quantum yield of the quantum dots.
