Site Isolation of Emitters within Cross-Linked Polymer Nanoparticles for White Electroluminescence
The use of cross-linked polymer nanoparticles was explored to achieve site isolation of different emitters within a single emissive layer in an electroluminescent device. Encapsulation of the iridium emitters within the polymer nanoparticles led to the desired effect with minimal energy transfer fro...

| description | The use of cross-linked polymer nanoparticles was explored to achieve site isolation of different emitters within a single emissive layer in an electroluminescent device. Encapsulation of the iridium emitters within the polymer nanoparticles led to the desired effect with minimal energy transfer from high bandgap chromophores to lower bandgap ones. The nanoparticles were easily dispersed in organic solvent for film casting while preserving particle shape. They behave as light emitting “inks”, enabling the tuning of electroluminescence through simple changes in the ratios of nanoparticles in the emissive film. |
