Carbon Dot Functionalized Papers for the Selective Detection of 2,4,6-Trinitrophenol in Aqueous Solutions

<div>(a) Fluorescence emission spectra of CDs added with different concentrations of TNP. (b) Relationship between relative fluorescence intensity (log<i>I</i><sub>0</sub>/<i>I</i>) (<i>I</i><sub>0</sub> and <i>I</i> represent the fluorescence intensity of CDs in the absence and presence of TNP, respectively) and different concentrations of TNP. (c) Changes in fluorescence under UV light and visible to the naked eye after the addition of different concentrations of TNP.</div>
