Abstract Biomass-derived carbon dots (C-dots) are considered a very important carbon material in metal ion detection of
their small environmental impact, simple preparation process, and relatively low cost. A green approach for
synthesizing biomass-derived C-dots from Chenpi using a hydrothermal method without further processing is
proposed in the present study. The as-synthesized C-dots show excellent fluorescence properties, superior resistance to UV irradiation photobleaching, and high photostability in salt-containing solutions. The C-dots were
used in the form of label-free fluorescent probes for sensitively detecting Hg2+ selectively. The outcome relationship behaved linearly and was established based on a given range between 10–300 nM… More >
