The Emerging Development of Multicolor Carbon Dots

Small, Journal Year: 2022, Volume and Issue: 18(51)

Published: Nov. 3, 2022

Abstract As a relatively new type of fluorescent carbon‐based nanomaterials, multicolor carbon dots (MCDs) have attracted much attention because their excellent biocompatibility, tunable photoluminescence (PL), high quantum yield, and unique electronic physicochemical properties. The emission characteristics (CDs) obviously depend on the source precursor, reaction conditions, environment, which directly or indirectly determines CDs. Therefore, this review is first systematic classification summary multiple regulation methods synthetic MCDs reviews recent research progress in synthesis from variety precursor materials such as aromatic molecules, small organic natural biomass, focusing how different produce corresponding MCDs. This also introduces innovative applications fields biological imaging, light‐emitting diodes (LEDs), sensing, anti‐counterfeiting due to PL It hoped that by selecting appropriate adjustment methods, can inspire guide future design tailored MCDs, provide help for development multifunctional

Nuclear Magnetic Resonance Reveals Molecular Species in Carbon Nanodot Samples Disclosing Flaws

Angewandte Chemie International Edition, Journal Year: 2022, Volume and Issue: 61(20)

Published: Feb. 14, 2022

Carbon nanodots are currently one of the hot topics in nanomaterials world, due to their accessible synthesis and promising features. However, purification these materials is still a critical aspect, especially for syntheses involving molecular precursors. Indeed, presence unreacted species or small organic molecules formed during solvothermal treatments can affect properties synthesized nanomaterials. To illustrate extreme importance this issue, we present two case studies which insufficient results misleading conclusions regarding chiral fluorescent investigated materials. Key identify use nuclear magnetic resonance, proves be an effective tool. Our work highlights need include resonance as standard characterization technique carbon-based nanomaterials, minimize risk observing that arise from species, rather than target carbon nanodots.

Published: March 18, 2024

Abstract Technologies that can simultaneously generate electricity and desalinate seawater are highly attractive required to meet the increasing global demand for power clean water. Here, a bifunctional solar evaporator features continuous electric generation in without salt accumulation is developed by rational design of polyelectrolyte hydrogel‐functionalized photothermal sponge. This not only exhibits an unprecedentedly high water evaporation rate 3.53 kg m −2 h −1 along with 98.6% energy conversion efficiency but also uninterruptedly deliver voltage output 0.972 V current density 172.38 µA cm high‐concentration brine over prolonged period under one sun irradiation. Many common electronic devices be driven simply connecting units series or parallel any other auxiliaries. Different from previously proposed mechanism, this study reveals water‐enabled proton concentration fields intermediate region induce additional ion field free containing solute, further enhance output. Given low‐cost materials, simple self‐regeneration design, scalable fabrication processes, stable performance, work offers promising strategy addressing shortages sustainable electricity.
