Title: NICKEL OXIDE FILM AND PREPARATION METHOD THEREFOR, FUNCTIONAL MATERIAL, MANUFACTURING METHOD FOR FILM STRUCTURE AND ELECTROLUMINESCENT DEVICE
Abstract:
A nickel oxide film and a preparation method therefor, a functional material, a manufacturing method for a film structure and an electroluminescent device. The nickel oxide film comprises: a nickel oxide film layer; and organic molecules having electron withdrawing groups, the organic molecules being connected and provided on the surface of the nickel oxide film layer. Due to the presence of the organic molecules having electron withdrawing groups, an electrical field that is reverse to the electrical field of the nickel oxide is established on the surface of the nickel oxide, and the surface work function of the nickel oxide film is thus improved. When the nickel oxide film with a high surface work function is used in a QLED device or an OLED device, the hole injection rate is improved.
