Abstract: A highly efficient fluorosensor based on ultrathin graphitic carbon nitride (g-C₃N₄) nanosheets for Cu(2+) was developed. In the absence of metal ions, the nanosheets exhibit high fluorescence; the strong coordination of the Lewis basic sites on them to metal ions, however, causes fluorescence quenching via photoinduced electron transfer leading to the qualitative and semiquantitative detection of metal ions. This fluorosensor exhibits high selectivity toward Cu(2+). The whole detection process can be complete… Show more

“…For example Huang et al [30] reported the g-C 3 N 4 nanofilms as a solid fluorescence sensor that are capable of convenient, sensitive, selective, rapid and recyclable sensing of Cu 2+ and Ag + in water and serum. Tian et al [31] developed a highly efficient fluorosensor based on ultrathin graphitic carbon nitride (g-C 3 N 4 ) nanosheets for Cu 2+ .…”

“…16 However, only a few reaserches have been carried out on its application in optical detection of envinonmental metal ions, 17,18 furthermore, as regards the application of g-C 3 N 4 in ECL detection of envinonmental metal ions (especially Cu 2+ ), the relative paper has been scarcely reported untill now, which is limited by the low ECL signal of g-C 3 N 4 . Though some oxidising coreactants (e.g.…”

“…In the last few years, plenty of researchers tried to prepare various g-C 3 N 4 with abundant micro/nanostructures and morphologies, which are availed for enhancing the dispersity and properties of g-C 3 N 4 . For example, ultrathin g-C 3 N 4 nanosheets prepared by exfoliating bulk g-C 3 N 4 materials [19][20][21] were negatively charged, and could be well dispersed in water. The exfoliation methods mainly include thermal oxidation exfoliation, ultrasonic exfoliation and chemical exfoliation.…”
