Stroyuk, Ya. Panasiuk, A. Raevskaya, S. Kuchmy] It was shown that graphitic carbon nitride (CN) produced at 500-725 °C can be exfoliated in aqueous solutions of tetraethylammonium hydroxide with the formation of stable colloids characterized by photoluminescence (PL) in the visible region of the spectrum. It was established that increase of temperature leads to decrease of the intensity of PL until it disappears completely at T > 675 °C. In the case of exfoliated CN the intensity of PL increases sharply with increase of temperature. This may be due to decrease in the size of the colloidal particles of CN, to the dynamics of internal conversion of electronic excitation in colloidal CN, and to the removal of peroxy groups from the core of the bulk CN in the course of exfoliation.
