Green Synthesis of Carbon Nanodots and Their Application in Specific Fluorescence Detection of Fe3+
was achieved. The morphology and microstructure of carbon nanodots were characterized by transmission electron microscope and X-ray photoelectron spectroscope
and the fluorescent performance of carbon nanodots was measured by fluorescent spectroscope. The results indicated that the prepared carbon nanodots showed good dispersity
and the average size was about 3 nm. When the reaction temperature was 200 ℃ and the reaction time was 12 h
the prepared carbon nanodots have the optimum fluorescent performance. Moreover
the introduction of Fe
3+
can quench the fluorescence of carbon nanodots
but other metal ions can not change the fluorescence intensity and emission wavelength of carbon nanodots
which indicates that the prepared carbon nanodots achieve specific fluorescence detection towards Fe
