Fluorescence spectra of TiO2 NP. (a) Toluene-dispersible SA-coated NPs. (b) Water-dispersible DMSA-coated NPs. The fluorescence spectra are deconvoluted into Gaussian line shapes. The experimental data are shown in solid circles. The dashed lines correspond to the individual components by Gaussian fitting, and the solid lines represent the sum of individual fitting lines.
