Summary: Using a solvent engineering strategy, full-color emissive carbon dots (CDs) were produced with excellent photoelectric properties and stable fluorescence performance. By tuning the volume ratio of water and dimethylformamide (H2O/DMF), the emission wavelengths of the CDs changed, and they exhibited stable fluorescence performance even after undergoing heating and UV light irradiation. Bright multicolor light-emitting diodes with a high color rendering index (CRI) were obtained using these CDs.

Summary: This work presents a facile synthesis method for near-infrared (NIR) emitting CuInS2/ZnS quantum dots (QDs). By using two sulfur precursors, 1-dodecanethiol (DDT) and hexamethyldisilathiane (HMDS), the reactive HMDS promotes faster nucleation and leads to a higher density of Cu-deficiency sites, resulting in QDs with high photoluminescence quantum efficiency (PLQE) of 65% at a long emission wavelength of 920 nm. NIR light-emitting diodes (LED) fabricated using these QDs achieve an external quantum efficiency (EQE) of 8.2%, comparable to the best reported PbS and InAs QD LEDs, and with an emission wavelength surpassing that of lead iodide perovskites. This work represents one of the first efficient NIR LEDs based on environmentally benign CuInS2 QDs, potentially enabling promising new applications in consumer electronic products.

Summary: Addressing the interactions between optical antennas and ensembles of emitters is challenging due to the complicating factors of charge transfer and Coulomb interactions. The study demonstrates how Au antennas enhance the luminescence of CdSe/CdS quantum dot assemblies through carrier dynamics control and plasmon-induced hot electron transfer. The research also shows that the localized surface plasmon resonances of Au antennas help tilt the balance between nonradiative Auger processes and radiative recombination in the CdSe core, leading to a high bright deep-red quantum dot light-emitting diode.
