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 ...

Advanced Optical Materials, EarlyView.A comparative study of the optical and polaritonic properties of excitons in hBN‐encapsulated monolayer TMDs close to the homogeneous linewidth is presented. Reflection spectroscopy with transmission‐line modeling enables extraction of the complex permittivities and demonstrate their ability to host surface‐exciton‐polaritons.

Enhancing Triplet Excitons Lifetime Through Controlled Intermolecular Interactions
Advanced Optical Materials, EarlyView.Singlet fission (SF) is investigated in pentacene embedded in a surface‐anchored metal–organic framework, enabling a molecular arrangement inaccessible in pure organic crystals. This architecture changes the singlet fission dynamics significantly and enhances the triplet lifetime by almost four orders of magnitude.
