Fluorescence spectroelectrochemistry for the study of electrochemiluminescence of the CdTe quantum dots/tripropylamine coreactant system

Abstract This study investigates the electrochemiluminescence (ECL) behavior of water-soluble cadmium telluride quantum dots (CdTe QDs) synthesized via a microwave-assisted hydrothermal method. The ECL response was examined in the presence of tri-n-propylamine (TPrA) as a coreactant, revealing two anodic ECL emissions, denoted as ECL 1 and ECL 2 , at potentials of + 0.85 V and + 1.2 V, corresponding to TPrA oxidation and CdTe QD oxidation, respectively. These emission intensities showed strong d
