Glucose-derived water-soluble crystalline graphene quantum dots (GQDs) with an average diameter as small 1.65 nm (∼5 layers) were prepared by a facile microwave-assisted hydrothermal method. The GQDs exhibits deep ultraviolet (DUV) emission of 4.1 eV, which is the shortest wavelength among all solution-based QDs. exhibit typical excitation wavelength-dependent properties expected in carbon-based dots. However, independent size GQDs. unique optical are attributed to self-passivated layer on...
Abstract CH 3 NH PbBr perovskite nanocrystals (PNCs) of different sizes (ca. 2.5–100 nm) with high photoluminescence (PL) quantum yield (QY; ca. 15–55 %) and product have been synthesized using the branched molecules, APTES 2 ‐POSS, as capping ligands. These ligands are sterically hindered, resulting in a uniform size PNCs. The effects from versus straight‐chain were compared possible mechanism proposed to explain dissolution–precipitation process, which affects growth aggregation PNCs,...
Rational design of multicomponent material structures with strong interfacial interactions enabling enhanced electrocatalysis represents an attractive but underdeveloped paradigm for creating better catalysts important electrochemical energy conversion reactions. In this work, we report metal–phosphide core–shell nanostructures as a new model electrocatalyst system where the surface electronic states shell phosphide and its reaction intermediates can be effectively influenced by core metal...
A new strategy has been developed using peptides with amino and carboxylic functional groups as passivating ligands to produce methyl ammonium lead bromide (CH 3 NH PbBr ) perovskite nanocrystals (PNCs) excellent optical properties. The well‐passivated PNCs can only be obtained when both are involved, this is attributed the protonation reaction between NH 2 COOH that essential for successful passivation of PNCs. To better understand synergistic effect, different lengths have studied...
Organolead bromide CH3NH3PbBr3 perovskite nanocrystals (PNCs) with green photoluminescence (PL) have been synthesized using two different aliphatic ammonium capping ligands, octylammonium (OABr) and octadecylammonium (ODABr), resulting in PNC–OABr PNC–ODABr, respectively. Structural studies by X-ray diffraction (XRD) transmission electron microscopy (TEM) determined that the PNCs exhibit cubic phase crystal structure average particle size dependent on ligand (3.9 ± 1.0 nm for 6.5 1.4...
Transition-metal phosphosulfides represent an emerging category of earth-abundant electrocatalyst materials, and some metal have been shown to outperform the corresponding sulfides phosphides. To fully realize potential benefit energy storage conversion, it is necessary study chemistry unknown phosphosulfide materials. In this article, we report on materials iron phosphosulfides. We systematically investigate synthesis, solid state chemistry, surface structures, electrocatalytic properties...

Mn-doped CsPbBr3 perovskite magic sized clusters (PMSCs) are synthesized for the first time using benzoic acid and benzylamine as passivating ligands MnCl2·4H2O MnBr2 Mn2+ dopant sources at room temperature. The same approach is used to prepare quantum dots (PQDs). concentration of MnX2 (X = Cl or Br) affects excitonic absorption PMSCs PQDs. A higher favors over PQDs well photoluminescence (PL) yields (QYs) PL stability. large ratio between characteristic Mn emission (∼590 nm) host band-edge...
