Title:
ORGANIC ELECTROLUMINESCENT DEVICES
Document Type and Number:
WIPO Patent Application WO/2023/149759
Kind Code:
A1
Abstract:
The present invention relates to a light-emitting layer for use in an organic electroluminescent device, wherein the light-emitting layer is obtained from co-evaporation of a composition comprising a mixture of two structurally different compounds both having an evaporation temperature between 150 to 400 °C. Furthermore, the invention refers to a method for preparing such light-emitting layer.
