A novel synthesis of CdSe nanocrystals is presented, which is based on the lower temperature reaction between TOPSe and cadmium acetate. An oleic acid/dodecylamine solvent was employed for studying the growth kinetics of CdSe nanoparticles at 200°C. The concentration of growing particles remained constant following the initial nucleation step. The diameter of the CdSe nanocrystals varied from 2.0±0.1nm up to 3.7±0.2nm. About 90% of the available Cd was consumed during the growth. The rate constant for steady-state CdSe deposition was found to be 9.74×10 −10 ms −1 at 200°C.
