Cadmium sulfide nanoparticles capped with thioglycolic acid as an organic ligand were synthesized by solution chemistry. Temporal evolution was studied by optical absorption, fluorescence, TEM, FTIR and x-ray diffraction measurements to understand the growth and stability of nanocrystals/ligand composites. The results suggest that besides being a good capping agent, thioglycolic acid also acts as an effective passivating ligand for electronically active surface states of CdS nanoparticles. Such binding quenches surface recombination and improves excitonic (band-to-band) recombination. This makes CdS nanoparticles an attractive material for certain applications wherein surfaces states are to be eliminated.
