Title:
ORGANIC ELECTROLUMINESCENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/058516
Kind Code:
A3
Abstract:
The present invention relates to organic electroluminescent devices comprising one or more light-emitting layers B, each of which is composed of one or more sublayers comprising as a whole one or more excitation energy transfer components EET-1, one or more excitation energy transfer components EET-2, one or more small full width at half maximum (FWHM) emitters SB emitting light with an FWHM of less than or equal to 0.25 eV. Furthermore, the present invention relates to a method for generating light by means of an organic electroluminescent device according to the present invention.
