Optical Properties of Fully Inorganic Core/Gradient-Shell CdSe/CdZnS Nanocrystals at the Ensemble and Single-Nanocrystal Levels

We report the synthesis and optical characterization of fully inorganic gradient-shell CdSe/CdZnS nanocrystals (NCs) with high luminescence quantum yield (QY, 50 %), which were obtained by replacing native oleic-acid (OA)...

Electrochemiluminescence of water-dispersed nitrogen and sulfur doped carbon dots synthesized from amino acids

A facile one-pot hydrothermal approach of synthesizing water-dispersed nitrogen and sulfur doped carbon dots (NS-CDs) with high luminescence quantum yield was explored, using cysteine and tryptophan as precursors. The NS-CDs...

Ancillary ligand modulated stereoselective self-assembly of triple-stranded Eu(iii) helicate featuring circularly polarized luminescence

Chiral ancillary ligands (R/S-BINAPO) modulated the stereoselective self-assembly of lanthanide helicates, which presented strong CPL with |glum| values up to 0.112 and high luminescence quantum yield up to 34%.

Suppressing the Defects in Cesium-Based Perovskite via Polymeric Interlayer Assisted Crystallization Control

Cesium-based inorganic metal-halide perovskites have attracted a great deal of scientific attention as effective emissive materials in light emission, due to their high luminescence quantum yield and outstanding thermal stability....
