Correction: A long-persistent phosphorescent chemosensor for the detection of TNP based on CaTiO₃:Pr³⁺@SiO₂ photoluminescence materials

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), (λ_Ex = 315 nm, λ_Em = 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. λ_Ex = 315 nm (error bars, SD, n = 3).
