Abstract
We developed and studied facile synthesis of graphitic carbon nitride in macroporous silica glass matrix. Melamine was used as a precursor. The synthesis was performed in a closed air ambience at 400–600∘C. It was found that the synthesized material was characterized with a broadband room-temperature photoluminescence in the range of 350–750[Formula: see text]nm with the peak shifting from to 445[Formula: see text]nm to 702[Formula: see text]nm when the temperature of the synthesis was increased from [Formula: see text]C to [Formula: see text]C while the intensity of the luminescence was decreased. The nature of the luminescent centers and possible applications of the synthesized material are discussed.
