Bisulfite induced chemiluminescence of g-C3N4 nanosheets and enhanced by metal ions

Abstract

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 Cu²⁺ ions can quench the fluorescence of g-C₃N₄ nanosheets as reported before.
