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.

Materials for Suppressed Triplet‐Polaron Quenching in Efficient and Long‐Lifetime Phosphorescent OLEDs

Advanced Optical Materials, EarlyView.
We performed a computational screening of phosphorescent emitters and charge transporters for OLEDs to identify combinations that minimize triplet‐polaron quenching, a major cause of efficiency loss and short operational lifetimes, especially in blue OLEDs. Our results reveal key design rules and highlight emitter‐transporter pairs that strongly reduce

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

Chameleonic Color‐Variable Microbead Emitters for Multilevel Spectroscopic Encryption from Visible to Infrared Wavelengths

Advanced Optical Materials, EarlyView.
Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,

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 ...
