Chemiluminescence of black phosphorus quantum dots induced by hypochlorite and peroxide

Abstract

For the first time, black phosphorus quantum dots (BP QDs) were found to show chemiluminescence (CL) properties in the presence of hydrogen peroxide (H₂O₂) and hypochlorite (ClO⁻). Excited phosphorus oxides (HPO) resulting from the oxidation of BP QDs account for CL emission. Taking triacetone triperoxide (TATP) as an example, the potential application of a new CL system was evaluated. This work sheds new light on the characteristics and broader applications of black phosphorus (BP).
