Tunable Photoluminescent and Photothermal Properties of Organic Cocrystals Containing Hydrogen‐Bonded Interlocked Planar Molecules

Advanced Science, EarlyView.
Engineering intramolecular hydrogen‐bonded planar architectures provides a versatile strategy for modulating the photoluminescent and photothermal behaviors of organic cocrystals. This work not only overcomes the limitations of selecting conjugated (hetero)aromatic compounds to meet the requirements of planarity and rigidity for cocrystal precursors ...

Electrically and Geometrically Tunable Photon Pair Entanglement from Ferroelectric Nematic Liquid Crystal

Advanced Science, EarlyView.
By exploiting the strong nonlinear optical response and controllable molecular ordering of ferroelectric nematic liquid crystals (FNLCs), these materials can serve as tunable sources of polarization‐entangled photons. Adjusting the sample geometry or applying an external electric field enables continuous control of the entanglement degree, advancing ...

Type‐I Heterostructure CdZnS/ZnS Core/Shell Quantum Dots Scintillators for Stable, High‐Resolution, and Real‐Time X‐Ray Imaging

Advanced Science, EarlyView.
Ultra‐bright Cd0.27Zn0.73S/7 ML‐ZnS core/shell quantum dots exhibit a photoluminescence quantum yield exceeding 96% and a fourfold enhancement in radioluminescence intensity compared to CsPbBr3. Variable‐temperature photophysical analysis reveals that the narrowband emission originates from direct recombination of edge excitons.
