Abstract
Correction for ‘A long-persistent phosphorescent chemosensor for the detection of TNP based on CaTiO3:Pr3+@SiO2 photoluminescence materials’ by Fangfang Li et al., RSC Adv., 2018, 8, 16603–16610.
In Fig. 2(C) of the published paper the colours of the lines were switched. A correct version of the figure is shown below:

| Fig. 2 (A) Phosphorescence excitation (Ex) and emission spectra (Em) of CaTiO3:Pr3+@SiO2 (30 μg mL−1) in PBS solution (10 mM, pH = 8.0), (λEx = 315 nm, λEm = 614 nm). (B) Phosphorescence spectra of 30 μg mL−1 CaTiO3:Pr3+@SiO2 with (red curve) and without (black curve) 200 μM TNP. Inset: temporal change in the phosphorescence intensity of CaTiO3:Pr3+@SiO2 after the addition of TNP. Effect of (C) pH and (D) salt concentration on the phosphorescence intensity of CaTiO3:Pr3+@SiO2 (30 μg mL−1) in the absence (black line) and presence (red line) of 200 μM TNP. λEx = 315 nm (error bars, SD, n = 3). | ||
