Optoelectronically Active GaAs/GeSn‐MQW/Ge Heterojunctions Created via Semiconductor Grafting

Advanced Optical Materials, EarlyView.
Semiconductor Grafting enables a lattice‐mismatched GaAs/GeSn‐MQW/Ge heterojunction with engineered band offsets and optical field distribution. The enlarged conduction and valence band discontinuities govern asymmetric carrier transport, producing bias‐dependent dual‐mode photodetection from visible to near‐infrared wavelengths.

Degradation of Blue MR‐TADF OLEDs: Host‐dependent Effects of mCBP and MADN Revealed by Fragmentation Profiling

Advanced Optical Materials, EarlyView.
Degradation in blue MR‐TADF OLEDs originates from high triplet density caused by slow RISC. LDI‐TOF MS directly detects host‐ and emitter‐derived fragments, providing molecular insight into how triplet accumulation drives degradation in the emissive layer. ABSTRACT Blue organic light‐emitting diodes (OLEDs) employing multi‐resonance thermally activated

Flexible and High‐Performance Perovskite‐Polymer Composites for Dual X‐Ray and Proton Direct Detection

Advanced Optical Materials, EarlyView.
A polymer–perovskite composite obtained by mechanochemical synthesis enables thick, tunable active layers for efficient absorption of highly penetrating ionizing radiation. Vertical‐electrode detectors achieve low X‐ray detection limits and high sensitivity direct 5 MeV proton sensing.

Metal‐Metal‐π Interaction: A Pathway to Construct Organic–Inorganic Excited‐State and Supramolecular Assembly

Advanced Optical Materials, EarlyView.
An organic–inorganic mixed excited state is designed and demonstrated by combining the metal–metal and π–π interactions within a supramolecular Pt2–pyrene assembly. Directional orbital overlap between the Pt and carbon atoms gives rise to a long‐lived triplet emission, strong emission polarization, exciton–exciton annihilation, and efficient exciton ...

Structural Modulation of Charge Transfer in Donor–Acceptor Systems: Effects of Donor Type and Connectivity

Advanced Optical Materials, EarlyView.
A coherent phthalimide acceptor platform with planar (Cz—carbazole) and spiro‐type (SAF—spiroacridine fluorene) donors enables systematic tuning of donor geometry and coupling, driving the evolution of excited‐state topology from classical CT‐TADF and fluorescence/RTP to CT‐driven and LE‐assisted TADF with OLED efficiencies ≈ 36%.
