Anthocyanin-Sensitized TiO₂ Nanoparticles for Phenazopyridine Photodegradation under Solar Simulated Light

Figure 6

Photoluminescence spectra measured for rutile TiO₂: (A) prepared, (B) commercial TiO₂ samples, and (C) AC/TiO₂. All spectra were measured as suspensions using excitation wavelength = 360 nm.
