Based on the photoluminescent property of carbon nanodts (CNDs), "on-off-on"-type response mechanisms were explored for the development of photoluminescent detection system. CNDs were obtained by an electric furnace combustion method of amino-acid analogues as a carbon source. CNDs were found to show stable photoluminescence under several pH and ionic strength conditions. Significant photoluminescent quenching of CNDs were recognized in the presence of oxidizing inorganic anions. The irreversible oxidation of functional groups on the CNDs surface were caused by hypochlorite and permanganate. The inner-filter effect was confirmed for the case of dichromate. These results presence evidence of the possibility for the reversible control of photoluminescent intensity of CNDs with dichromate and reducing agents.
