Materials for optics are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each task is strongly wavelength dependent, thus a full understanding of the interaction between light and matter is vital.
A single light-emitting dye molecule precisely placed within the tiny gap of a metal nanodimer boosts light–matter coupling — a step closer to the development of quantum devices operating at room temperature.
Robin Neuder and colleagues investigate liquid crystals for phase tuning in reconfigurable intelligent surfaces based on defected delay lines. This approach enables liquid crystal reconfigurable intelligent surfaces that can be optimized towards wide bandwidth, low loss, and fast response time simultaneously.
Efficient organic light-emitting diodes require a multilayer architecture to confine charge recombination to the emissive layer. Here, authors demonstrate efficient single-layer devices for emitters with imbalanced charge transport without the need of additional charge transport or blocking layers.
Exploiting the interactions between bright excitons and free carriers in an atomically thin semiconductor of trilayer tungsten diselenide WSe2 results in Fermi polarons that exhibit unusually large nonlinearity.
A single light-emitting dye molecule precisely placed within the tiny gap of a metal nanodimer boosts light–matter coupling — a step closer to the development of quantum devices operating at room temperature.
Highly efficient matrix-free hyperfluorescent organic light-emitting diodes are constructed with remarkably supressed Dexter transfer utilizing narrowband blue emitters encapsulated with hopped alkyl chains.
Properly maintaining the skin temperature is critical for wound healing, especially outdoors. Now, a lightweight and skin-friendly wound dressing is reported that can continuously cool the skin without energy input.
Even by shining classical light on a single opening, one can perform a double-slit experiment and discover a surprising variety of quantum mechanical multi-photon correlations — thanks to surface plasmon polaritons and photon-number-resolving detectors.
