Chemiluminescence studies between aqueous phase synthesized mercaptosuccinic acid capped cadmium telluride quantum dots and luminol-H2O2

• Mercaptosuccinic acid capped Cadmium telluride quantum dots were synthesized via aqueous phase method.
• To explore the resonance energy transfer, chemiluminescence experiments were performed between luminol-H2O2 and CdTe QDs.
• A dramatic reduction in the fluorescence quantum yield is noticed while compared to pristine CdTe QDs.

Mercaptosuccinic acid capped Cadmium telluride quantum dots have been successfully synthesized via aqueous phase method. The products were well characterized by a number of analytical techniques, including FT-IR, XRD, HRTEM, and a corrected particle size analysis by the statistical treatment of several AFM measurements. Chemiluminescence experiments were performed to explore the resonance energy transfer between chemiluminescence donor (luminol-H2O2 system) and acceptor CdTe QDs. The combination of such donor and acceptor dramatically reduce the fluorescence while compared to pristine CdTe QDs without any exciting light source, which is due to the occurrence of chemiluminescence resonance energy transfer (CRET) processes.
