Abstract
In this study, we have obtained uniform and high quality Cu 2 ZnSnS 4 (CZTS) nanocrystals which were synthesized by using the hot injection method. The effect of injection rate on growth mechanism was investigated. The injection rates were varied from 2.5 to 20mL/h. The CZTS nanocrystals were characterized by TEM, XRD, and Raman. The Raman spectrum revealed good crystallinity, and TEM images showed uniform dispersion. As the injection rates increased, the CZTS particles size become larger and less uniform, which was consistent with LaMer model. The composition of CZTS nanocrystals was almost close to stoichiometry, and we obtained the CZTS nanoparticles with good crystallinity for the case injected at 10mL/h. © 2013 IEEE.
