Growth Kinetics of CdSe Nanoparticles in Lauric Acid

Abstract:

A safe, common, and low-cost method was proven to be effective for the synthesis of high quality CdSe nanocrystals. Cd(Ac)2 and Lauric acid were found to be the excellent cadmium precursor and solvent/ligand, respectively. The size and shape of CdSe nanocrystals synthesized by this route can be varied in a controllable manner in a broad size range, from about 2.0 nm to 4 nm. The growth kinetics of CdSe nanocrystals nucleated from TOPSe and cadmium acetate was also investigated in Lauric Acid. The rate constant for steady-state CdSe growth was found to be 4.15×10─8 m s─1 at 260°C.
