In this communication, a novel chemiluminescence phenomenon was observed for the as-prepared carbon nanodots (CDs) in a concentrated sodium hydroxide (NaOH) solution. The generation of superoxide anion radical (O2˙(-)) directly provides evidence for the excellent electron-donating ability of CDs.
In this work, a novel chemiluminescence (CL) phenomenon was found: a g-C3N4 nanosheets suspension was mixed with NaHSO3 solution directly to produce luminescence, and the intensity of luminescence could be obviously enhanced by some metal ions, which was distinctly different from the phenomenon that Cu(2+) ions can quench the fluorescence of g-C3N4 nanosheets as reported before.
Fluorescent carbon nanoparticles (FCNs), as novel luminescent reagents exhibiting hydrogen peroxide mimicking properties, can directly react with luminol, NaHCO and NaHSO in alkaline conditions to yield novel chemiluminescence, and show great potential towards further applications of ultra-weak chemiluminescence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
