Efficient White Electrochemiluminescent Emission From Carbon Quantum Dot Films.

ABSTRACT: Carbon quantum dots (CQDs) were manufactured from citric acid and urea in a gram-scale synthesis with a controlled size range between 1. 5 and 23.8 nm. The size control was realized by varying volume of the precursor solution in a hydrothermal synthesis method. The prepared CQDs were investigated using electrochemiluminescence (ECL) spectroscopy at interfaces of their electrode films and electrolyte solution containing coreactants rather than conventional optoelectronic tests, providing an in-depth analysis of light-emission mechanisms of the so-called half-cells. ECL from the CQD films with TPrA and K₂S₂O₈ as coreactants provided information on the stability of the CQD radicals in the films. It was discovered that CQD^•- has a powerful electron d
