Luminescent carbon quantum dots (CQDs) prepared from aqueous beetroot extract were developed as unique fluorescent nanomaterials for <italic>in vivo</italic> live animal imaging applications.
Abstract A mixture of extracts from two common vegetables, red pomegranate and turmeric, when photoexcited at 380 nm, produced almost pure white light emission (WLE) with Commission Internationale d’Eclairage (CIE) chromaticity index (0.35, 0.33) in acidic ethanol. It was also possible to obtain WLE polyvinyl alcohol film (0.32, 0.25) gelatin gel (0.26, using the same extract mixture. The colour temperature conveniently tunable by simply adjusting concentrations component emitters. primary...
Water contamination due to the presence of lead is one leading causes environmental and health hazards because poor soil groundwater waste management. Herein we report synthesis functionally modified luminescent carbon quantum dots (CQDs) obtained from watermelon juice as potential nanomaterials for detection toxic Pb2+ ions in polluted water cancer cells. By introducing surface passivating ligands such ethanolamine (EA) ethylenediamine (ED) juice, watermelon-ethanolamine (WMEA)-CQDs...
White light emission was produced upon 380 nm photoexcitation from a mixture of pomegranate extract and carbon nanoparticles made the in aqueous acidic (pH 1.2) solution as well polyvinyl alcohol polymeric film with good Commission Internationale del’Eclairage (CIE) index values (0.28, 0.33) (0.33, 0.29) respectively.
Herein, blue-emitting carbon nanoparticles (CNPs) were synthesized using the
Abstract Scaling up the synthesis of fluorescent silica nanoparticles to meet current demand in diverse applications involves technological limitations. The present study relates hydrothermal water-soluble, crystalline, blue-emitting amine-functionalized from coal fly ash sustainably and economically. This used tertiary amine (trimethylamine) prepare nanoparticles, enhancing fluorescence quantum yield nitrogen content for nanofertilizer application. TEM FESEM studies show that have a...
The luminescent solar concentrator is the most helpful tool for increasing power conversion efficiency of photovoltaic cell through harvesting mechanism. However, scalability, efficiency, design, and cost-effectiveness remain...
A new class of novel conjugated and highly fluorescent isobenzotriazolophanes containing electron-rich N-heterocyclic moieties, such as pyrrole, indole carbazole, were synthesized for the first time through McMurry coupling. The carbazole-based isobenzotriazolophane with a quantum yield 0.38 showed positive response to quenching electron-deficient aromatic nitro compounds, picric acid (PA), selectively at micromolar concentration. Stern–Volmer constant is 8.82 × 102 M−1 limit detection (LOD)...
A facile synthesis and detailed photophysical investigation of E/Z-isomerization fluorescent diphenylamine tethered stilbene derivatives (DPASs) under white light exposure have been carried out to understand the effect on fluorescence, electrochemical properties, photostability various activation/deactivation pathways. In solution state, in dark, E-isomer DPASs (6a–d) exhibited high fluorescence quantum yields (Φfl ≈ 53% 60% DMSO). However, exposure, 1H NMR HPLC studies revealed that pure...
Developing reliable biocompatible bioimaging agents is paramount for diagnosing critical diseases and disorders early through oral ingestion of fluorescent probes to image living organisms. Here, we prepared fluorescent, water-dispersed graphene oxide quantum dots
Abstract The synthesis of novel contrast agents based on carbon nanomaterials is garnering significant attention because their unique properties, such as biocompatibility, ease fabrication, colloidal stability, and low cost. This article describes a possible sustainable approach for developing blue‐emitting fluorescent nano‐onions from low‐quality Indian coal using simple mild acid oxidation. high‐resolution transmission electron micrograph prepared reveals the crystalline graphitic...
Aqueous zinc batteries are increasingly gaining attention of the researchers in recent years because their environmental and user friendliness as well economic benefits metal. Herein we report a ferrocene based organic cathode synthesized by following green chemistry principle stabilized low temperature thermal encapsulation multiwalled carbon nano tubes (MWCNTs) for stable electrochemical performance. Successful intercalation was confirmed XRD, Raman, FTIR spectra, TEM-HAADF imaging....
