Abstract

Synthesis of highly stable green light emitting CdTe quantum dots in aq. medium is discussed. The absorption spectroscopy revealed formation of dots of the size about 4 nm. Effect of pH controlling reagents, capping agent and reaction time is studied. Highly stable CdTe of about 3 nm size with excellent fluorescence are synthesized in aqueous medium in about 30 min. The CdSe layer was successfully deposited around CdTe core to eventually isolate re-dispersible cubic CdTe/CdSe core/shell QDs.
