CdTe nanocrystals were synthesized in aqueous solution with thioglycolic acid (TGA)
L-cysteine (L-Cys)
3-mercaptopropionic acid (MPA) and 1-thioglycerol (TG) as stabilizers. We systematically investigated the effect of different stabilizers on the optical properties of CdTe nanocrystals and the stability of spherical CdTe nanocrystals and nanorods. The results indicate that different shapes
absorption spectrum and PL emission spectrum of CdTe nanocrystals can be obtained with using different stabilizers contained TGA
MPA
TG and L-Cys. It is due to the influences of stereo-hindrance effect and functional groups of different stabilizers.
