Abstract
Correction for ‘Highly photoluminescent nitrogen-rich carbon dots from melamine and citric acid for the selective detection of iron(III) ion’ by Shaoqing Liu et al., RSC Adv., 2016, 6, 31884–31888, https://doi.org/10.1039/C5RA26521E.
In the original manuscript, the authors regret an error in the vertical axis label for Fig. 3c. The vertical axis was mistakenly labelled as “Abs” rather than “F”. A correct Fig. 3 is provided below.

| Fig. 3 (a) UV/Vis absorption spectra of the N-rich CDs; (b) PL emission spectra of NCDs-240 with progressively increased excitation wavelengths from 260 to 380 nm with 20 nm increment. Inset of (b) is the optical image of NCDs-240 suspensions with strong blue luminescence under the excitation at 365 nm; (c) normalized emission spectra of N-rich CDs under the maximum excitation wavelength of 320 nm; (d) PL intensity of NCDs-240 in the solutions with different pH values. | ||
The conclusions remain unaffected by this change.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
