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 ...

Substituent Effects on Cyanine Dyes Vary with Position and Chain Length

Advanced Optical Materials, EarlyView.
In cyanines, substituent effects vary as a function of substituent position and cyanine length. Electron‐donating‐ and ‐withdrawing groups at meso‐ and α‐positions of 4n+1/4n−1 long cyanines (n = 1, 2, 3…) cause opposing, hypsochromic and bathochromic shifts of the 1st UV–vis absorption bands.

Long-Distance Quantum Communication with Entangled Photons using Satellites

, 2003
The use of satellites to distribute entangled photon pairs (and single photons) provides a unique solution for long-distance quantum communication networks. This overcomes the principle limitations of Earth-bound technology, i.e. the narrow range of some

Photonics of Topological Magnetic Textures

Advanced Optical Materials, EarlyView.
Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...
