An aqueous synthesis method was developed for the successful production of water-soluble CdTe quantum dots capped with thioglycolic acid and L-cysteine. Through evaluation of absorption and fluorescence spectrums as well as fluorescent quantum yield, it was found that the best ratio of the two buffers was TGA:L-cys = 1:1. This ratio produces quantum dots with high fluorescent intensity and a large fluorescent wavelength range with the potential to continue growing. The quantum dots produced were found to have possible application in the field of environmental monitoring.
