[22] used an anthocyanin-rich extract with TiO2 thin films for the photocatalytic degradation of methylene blue. Harnchana et al. [24] used poly (N-vinylcarbazole) (PVK) as an additive in the I−/I−3 redox electrolyte and studied the photoelectrochemical effect of PVK with various ...
At pH = 2 the C-dots showed λmax = 385 nm (QY = 43.0%), but at pH = 3 a weak red peak appeared along with the dominant blue peak. Upon increasing the pH, the intensity of the blue emission peak declined, whereas the red emission peak was enhanced, and at pH = 7 there was...
