Multicolor emissive nitrogen-doped carbon quantum dots (CQDs) were synthesized by the hydrothermal method and characterized using spectroscopic electron microscopic techniques. Förster resonance energy transfer (FRET) between CQDs gold nanorods (AuNRs) has been investigated that occurs due to distinctive overlap of transverse longitudinal bands AuNRs with fluorescence (FL) spectra CQDs. Significant FL quenching (turn-off) their recovery (turn-on) have observed etching end-to-end assemblies lead detection biomolecules like H2O2, glucose, glutathione (GSH), acetylcholinesterase (AChE). The redox reaction Au(0) H2O2 results in decomposition give Au(I) ions, thereby inducing (turn-on). interruption FRET phenomenon production from glucose oxidase presence a thiol-containing compound acetylthiocholine AChE enzyme causes CQDs, respectively. Moreover, assembly leads disruption, turn-on signals found be measures GSH. In comparison UV–visible approach, measurements through process are more sensitive under same conditions. practical applicability proposed sensing system verified human plasma samples.

Abstract Carbon dots (CDs)—carbon nanoparticles smaller than 10 nm—have attracted widespread attention owing to their excellent optical properties. However, high‐performing CDs often suffer from severe aggregation‐induced quenching in the solid state, which limits commercial applicability. Therefore, CD materials with efficient solid‐state luminescence are sought. As research on structure and photoluminescence mechanisms of has intensified recent years, strategies construct fluorescent tune emissions have broadened. This article reviews advances for attaining fluorescence CDs, describes specific ways properties this fluorescence, introduces latest applications resulting optoelectronics, biology, sensing, finally considers prospects future application current challenges facing development CDs.

Fluorescence regulation of carbon dots (CDs) during their preparation has become a hot research topic. In this work, multicolor fluorescent CDs with unconventional luminescence behavior are prepared by using o-, m-, or p-phenylenediamine (o-PD, m-PD, p-PD, respectively) and 2,3-dihydroxynaphthalene rich hydroxyl groups as reaction precursors. Tunable bright blue, yellow, red colors can be obtained solvothermal method under the joint action ethanol hydrochloric acid. The fluorescence emission synthesized follows rule o-PD to m-PD p-PD from blue red, which is contrary most previously reported results (the following an order p-PD). Our reveal that differences in polymerization, surface states, functional groups, graphite N content might main reasons for behavior. addition, these have good applications fields light-emitting diode lighting anticounterfeiting.
