Figure 7

(a) Typical PL quenching of LCD-160 in the presence of Be2+ ions; (b) Typical PL quenching of LCD-160 in the presence of Fe3+ ions; both the insets are concentration-dependent fluorescence response. (c) Performance of sensors based on prepared carbon dots: comparison of fluorescence intensities in the absence and presence of different metal ions.
