Abstract
The present application relates to a technical filed of energy sources and illumination, and discloses a rare earth oxide nanosheet composite modified by an organic ligand, a preparation method and an organic light-emitting diode (OLED) luminescent film. The rare earth oxide nanosheet composite modified by the organic ligand is obtained by adding the organic ligand in the rare earth nanosheet sol for ultrasonic coordination; and a mole ratio of the rare earth nanosheet sol to the organic ligand is 1:(3-9).
