Reverse Intersystem Crossing and Exciton Harvesting: A Pathway to Low Threshold in Multi‐Resonant TADF Electrically Pumped Organic Semiconductor Lasers

Advanced Optical Materials, EarlyView.
Electrically pumped organic lasing thresholds are lowered by mitigating triplet accumulation through a tailored host‐guest system. Integrating the multi‐resonant TADF emitter DABNA‐2 into a triplet‐scavenging BSBCz host suppresses singlet‐triplet annihilation.

Solution‐Processed Spin‐Polarized Light‐Emitting Diodes of Colloidal Quantum Wells and Magnetic Nanoparticles

Advanced Optical Materials, EarlyView.
All‐solution‐processed spin‐LEDs based on colloidal Fe3O4 nanoparticles and CdSe/CdZnS core/shell CQWs that allows for polarization modulation of electroluminescence are fabricated. With these devices, electrical injection of spin‐polarized carriers from the Fe3O4 nanoparticle layer into the CdSe/CdZnS CQWs is demonstrated, realizing circularly ...

Highly Efficient Pure‐Blue Single‐Layer Organic Light‐Emitting Diodes Without High‐Triplet‐Energy Auxiliary Materials

Advanced Optical Materials, EarlyView.
Blue organic light‐emitting diodes (OLEDs) comprising triplet‐harvesting emitters require the use of high‐triplet‐energy hosts and blocking layers to confine the triplet excitons to the emitter. Here, we present efficient single‐layer blue hyperfluorescent OLEDs comprising solely of a matrix‐free emissive layer between two charge‐injecting electrodes ...

Projector‐Induced Waveguide Encoded Lattices (ProWELs) with Optical Functionality: From Enhanced Fields of View (FOV) to 3D Data Encoding

Advanced Optical Materials, EarlyView.
We describe the fabrication of 3D polymeric waveguide architectures with tunability of waveguide diameter, lattice symmetry and long and short‐range order using an inexpensive (< $400 CAD) digital light projector. We demonstrate that Projector induced Waveguide Encoded Lattices (ProWELs) possess advanced functionality including tuneable Fields of View (

White Organic Light Emitting Diodes

, 2011
Die vorliegende Arbeit beschäftigt sich mit drei Ansätzen der hocheffizienten Erzeugung von weißem Licht mit organischen Leuchtdioden (OLEDs) auf der Basis kleiner Moleküle. Ein Ansatz kombiniert die Emission eines fluoreszenten und zweier phosphoreszenter Emitter in einer einzelnen Emissionsschicht.
