White-light-emitting carbon dots (WCDs) show innate advantages as phosphors in white light-emitting diodes (WLEDs). For WLEDs, the color rendering index (CRI) is most important metric to evaluate its performance. Herein, WCDs are prepared by a facile one-step solvothermal reaction of trimellitic acid and o-phenylenediamine. It consists four CDs identified column chromatography blue, green, yellow, red, thus light superposition these types light. The mixture undergoes Förster resonance energy...
Abstract Afterglow materials have attracted much attention owing to their long luminescence lifetimes, large Stokes shifts, and emission without real‐time excitation. Compared with traditional organic afterglow materials, carbon dots (CDs), as a new material, superior properties such easy preparation, low toxicity, cost. The color of CDs can be regulated by external factors excitation wavelength, temperature, time, which is highly significant for expanding the diversified applications make...
Photoluminescent organosilane-functionalized carbon quantum dots (CQDs), 3.0–3.5 nm in diameter, were synthesized via a facile hydrothermal method using citric acid monohydrate as precursor and N-(3-(trimethoxysilyl) propyl) ethylenediamine coordinating passivation agent. The optical properties of the as-obtained CQDs investigated detail. CQD aqueous solution emits bright blue-white light under ultraviolet (UV) illumination with yield 57.3% high red-green-blue (RGB) spectral composition...
Highly fluorescent water-soluble and nitrogen-doped carbon dots (NCDs) were synthesized by a simple one-pot hydrothermal method using citric acid as source urea nitrogen source.
Carbon dots synthesized by a microwave-assisted hydrothermal method exhibit efficient solid-state luminescence for white light-emitting devices.
Ultrafine SnS2 nanocrystals-reduced graphene oxide nanoribbon paper (SnS2-RGONRP) has been created by a well-designed process including in situ reduction, evaporation-induced self-assembly, and sulfuration. The as-formed nanocrystals possess an average diameter of 2.3 nm disperse on the surface RGONRs uniformly. strong capillary force formed during evaporation leads to compact assembly give flexible structure with high density 0.94 g cm-3. as-prepared SnS2-RGONRP composite could be directly...
Zinc oxide (ZnO) is one of the most extensively used electron-transporting layers (ETLs) in organic solar cells. However, owing to numerous surface defects and mismatched energy bands with photoactive layer, light-soaking process usually required achieve a high device performance for ZnO-based Herein, we reported synthesis N,S-doped carbon quantum dots (N,S-CQDs) by simple hydrothermal treatment using ascorbic acid ammonium persulfate as reagents. As characterized high-resolution...
Carbon dots (CDs) have attracted a lot of attention because their tunable emission wavelength, high photobleaching resistance, and environmental friendliness. However, they suffer from aggregation-induced quenching in the solid state, which limits application solid-state fields. In this work, yellow- orange-emissive N, B-codoped CDs (y-NB-CDs o-NB-CDs) with highly efficient fluorescence dual were achieved by facile one-step microwave method. The obtained y-NB-CDs powder state show bright...
Carbon-based electric double layer capacitors (EDLCs) hold tremendous potentials due to their high-power performance and excellent cycle stability. However, the practical use of EDLCs is limited by low energy density in aqueous electrolyte sluggish diffusion kinetics organic or/and ionic liquids electrolyte. Herein, 3D carbon frameworks (3DCFs) constructed interconnected nanocages (10-20 nm) with an ultrathin wall ca. 2 nm have been fabricated, which possess high specific surface area,...
S-CQDs were chosen as a light emitting layer by virtue of their structure characteristics, optical properties and film-forming ability to obtain CQD-LEDs.
To greatly improve the production quality and efficiency of carbon quantum dots (CQDs), provide a new approach for large-scale high-quality CQDs, green (g-CQDs) with high product yield (PY) fluorescent (QY) were synthesized by an efficient one-step solvothermal method 2,7-dihydroxynaphthalene as source ethylenediamine nitrogen dopant in this study.
