Effective size control through solvents in microwave aided synthesis of GSH- CdTe quantum dots

Abstract

Highly luminescent GSH capped CdTe quantum dots (GSH-CdTe QDs) were prepared through a facile microwave (MW) aided wet chemical method. The mechanism of effective size control through the solvents is proposed. The Small angle X-ray scattering (SAXS) measurements show that the size dispersion of QDs can be precisely controlled through the selection of appropriate solvents. The high boiling point and high loss tangents were found to be effective in controlling the size dispersion in MW aided synthesis. The PL studies show that the sharpness of the emission peaks depends on the size dispersion.
