Synthesis of CdSe quantum dots

Water-soluble CdSe quantum dots (QDs) were synthesized in aqueous solution with thioglycollic acid as stabilizer.CdSe QDs were characterized using Transmission electron microscopy (TEM),UV-Vis absorption spectrum (UV-Vis) and fluorescence spectra (FL).The characterization results indicate that as-synthesized CdSe QD was uniform at about 3.5 nm.
