ELECTRON TRANSPORT LAYER INK, MANUFACTURING METHOD THEREFOR, AND ELECTROLUMINESCENT COMPONENT

WIPO Patent Application WO/2020/232769

A1

Provided are an electron transport layer ink, a manufacturing method therefor, and an electroluminescent component. The composition of the electron transport layer ink in terms of weight content percentage comprises an organic small molecule electron transport material 0.5 wt% to 30 wt%, an alkali metal complex-doped material 0.1 wt to 5 wt%, a surface tension regulator 0.1 wt% to 5 wt%, a viscosity regulator 0.1 wt% to 5 wt%, a polar mixed solvent 69 wt% to 99 wt%, and an auxiliary solvent 0.1 wt% to 30 wt%. The electron transport layer ink allows an electron transport layer to be formed via a printing technique and, at the same time, prevents the solvents in the electron transport layer ink from damaging a lower-level light-emitting layer.
