Illuminating Quantum Phenomena in 2D Materials: The Power of Optical Spectroscopy

Advanced Optical Materials, EarlyView.
Atomically thin 2D materials host quantum tunnelling, plasmonic and excitonic phenomena driven by reduced dimensionality and strong many‐body interactions. This review links these effects to state‐of‐the‐art optical probes—NSOM, pump–probe, CARS, TRR, and optical frequency comb spectroscopy—highlighting how their ultrahigh spatial–temporal resolution ...

On‐Chip Sensing with Slow Light Topological Cavities

Advanced Optical Materials, EarlyView.
A valley photonic crystal slow‐light sensor is demonstrated with up to 1.76‐fold shorter round‐trip path lengths than non‐slow‐light designs. The stronger light‐matter interactions in the slow‐light cavity sensor result in up to threefold higher sensitivity compared to the non‐slow‐light cavity sensor.

Enhancing Organic Light‐Emitting Diode Performance Using Naturally Derived Diatomite: A Cost‐Effective and Eco‐Friendly Strategy

Advanced Optical Materials, EarlyView.
Diatomite‐based light extraction structures enable enhanced photon outcoupling through multi‐angle scattering and far‐field redistribution. By harnessing the unique scattering behavior of diatomite, this approach introduces randomly oriented scattering centers that effectively reshape internal light propagation.
