CsPbCl3 nanocrystals are potential ultrapure emitters. But it is challenging to synthesize with sufficient stability, which impedes their application in light-emitting devices. In this work, we report a facile phosphoryl-chemistry-mediated synthesis approach synthesizing stable nanocrystals, the phenylphosphonic dichloride (PhPOCl2) precursor employed. addition high reactivity of P–Cl bond PhPO...

Abstract Silver bismuth sulfide (AgBiS 2 ) is showing impressive thermoelectric and photovoltaic properties has a high potential to replace toxic cadmium or lead containing semiconductors in many applications. Herein, we report on synthesis route for AgBiS nanocrystals applying metal xanthates as precursors. could not be used so far solution‐based syntheses Ag‐containing they are typically inso...

The synthesis of halide perovskite nanocrystals (PNCs) with mesmerizing photophysical properties has allowed for the fast development efficient optoelectronic and photovoltaic devices, as well making them ideal photocatalysts solar-driven chemical reactions. However, use traditional oleic acid/oleylamine low binding energy introduction some phosphine- sulfur-based ligands generate emergence hig...

A single source molecular precursor synthesis of new quinary Ag-In-Ga-Zn-S (AIGZS) QDs is presented. Dithiocarbamate complexes with varied Ag/In/Ga/Zn ratios were prepared from AgNO3, In(NO3)3, Ga(NO3)3 and Zn(diethyldithiocarbamate)2. The thermal decomposition these at 220 °C in oleylamine produces AIGZS emitting the visible to near-infrared region photoluminescence quantum yields (PL QYs) up ...

In this thesis, Cu2O nanochains were synthesized by thermal decomposition with copper formate-octylamine as the precursor, oleic acid and oleylamine catalyst stabilizer agent paraffin solvent. The phase structure micromorphology of characterized X-ray diffraction transmission electron microscopy. effect reaction time concentration precursor on discussed, formation mechanism was analyzed. result...

Solution-processed iron selenide nanocrystals (NCs) have recently attracted considerable attention in electrocatalysis water splitting. Nevertheless, a primary challenge current iron-based NCs chemical synthesis is controlling phase purities between each chalcogen (monochalcogenide, dichalcogenides, and oxides), which requires comprehensive understanding of the reaction mechanisms at early stag...

Fe3C/few-layered graphene core/shell nanoparticles embedded in a carbon matrix are synthesized by novel two-step surfactant sol-gel strategy, where the processes of hydrolysis, polycondensation and drying take place one-pot. The present approach is based on combined action oleic acid oleylamine, which act sterically precursor micelles when densification temperature performed reducing atmosphere...

Syntheses of transition-metal dichalcogenides (TMDs) using colloidal-chemistry approaches are gaining significant interest in recent years, as these methods enable the morphology and properties nanocrystals to be tuned for targeted applications. In this work, by only varying ligand used during synthesis, we synthesized nanoflowers with oleic acid (OA) 1T' phase dominated WSe2 nanosheets oleylam...

The development of sensor materials which gas sensitivity activates under light illumination is great importance for the design portable analyzers with low power consumption. In present work a ZnO/CsPbBr3 nanocomposite based on nanocrystalline ZnO and colloidal cubic-shaped perovskite CsPbBr3 nanocrystals (NCs) capped by oleic acide oleylamine was synthesized. individual obtained are characteri...
