Title:
THIN FILM AND PREPARATION METHOD THEREFOR, PHOTOELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/056838
Kind Code:
A1
Abstract:
The present application discloses a thin film and a preparation method therefor, a photoelectric device, and a display device. The thin film comprise a metal oxide nanomaterial doped with a triazine framework material. When the thin film is used as a hole transport layer, the triazine framework material enables better matching of the energy level of the hole transport layer and a light-emitting layer, thereby facilitating the balance of electron-hole injection, improving the conductivity of metal oxide nanoparticles, and increasing the hole transport rate, thus synergistically improving the luminous efficiency of the photoelectric device.
