Advanced Optical Materials, EarlyView.ZnGa2O4:Cr3+ nanoparticles with persistent luminescence are synthesized and optimized for labeling microplastics via cryomilling. The solvothermal method provides superior optical properties, enabling background‐free imaging. These luminescent particles are successfully used to trace microplastic uptake and distribution in Daphnia magna, offering a ...

Influence of ligand shape and steric hindrance on the composition of the nanocrystal ligand shell [PDF]
, 2015 Organic ligands play a key role in the synthesis of colloidal semiconductor nanocrystals or quantum dots. Generally they consist of a functional group and an aliphatic chain, with carboxylic acids, thiols and phosphonic acids as typical examples.

Advanced Optical Materials, EarlyView.Femtosecond TAS measurements on perovskite nanocrystals reveal how the one‐photon absorption cross‐section scales linearly with nanocrystal volume, independent of shape. In contrast, biexciton Auger lifetimes vary strongly with shape and remain constant in the weak confinement regime for nanocrystals larger than the exciton Bohr radius, offering new ...

Surface Oxidation of 2D γ‐Indium Sulfide Nanoplatelets and Its Impact on Photoluminescence
Advanced Photonics Research, EarlyView.Photoluminescence of defective 2D γ‐In2S3 can be modulated after exposure to air or oxygen‐containing ligands. Cryogenic photoluminescence measurements reveal that a new acceptor level is introduced upon oxidation, modulating the relative intensity of the emission bands.

Visible Light‐Promoted Esterification of Carboxylic Acids via Photoacid Generation Catalysis
Advanced Synthesis &Catalysis, EarlyView.A novel, environmentally friendly photochemical method for the esterification of carboxylic acids with alcohols using arylazo sulfones as photoacid generators was developed. This approach avoids traditional acidic catalysts, purification did not require chromatography and the method proved effective under continuous flow conditions for enhanced ...

Advanced Sustainable Systems, EarlyView.CsPbBr₃ colloidal nanocrystals synthesized via hot‐injection (HI) and microwave‐assisted (MW) methods exhibit excellent optoelectronic properties for LEDs. Although the MW route is more energy‐efficient and eco‐friendly in the lab, industrially, its environmental impacts are similar, but with lower costs.
