SPECTRAL EMISSION MODIFICATION USING LOCALIZED SURFACE PLASMON OF METALLIC NANOPARTICLES

Title:

SPECTRAL EMISSION MODIFICATION USING LOCALIZED SURFACE PLASMON OF METALLIC NANOPARTICLES

Document Type and Number:

WIPO Patent Application WO/2018/111974

Kind Code:

A3

Abstract:

A method for engineering a line shape of emission spectrum of an organic emissive material in an electroluminescent device is disclosed in which a layer of plasmonic metallic nanostructures having a localized surface plasmonic resonance (LSPR) is provided in proximity to the emissive layer and the layer of plasmonic metallic nanostructures is greater than 2nm but less than lOOnm from the emissive layer and the LSPR of the plasmonic metallic nanostructures matches the emission wavelength of the organic emissive material. An electroluminescent device incorporating the plasmonic metallic nanostructures is also disclosed.
