ChemInform Abstract: Synthesis and Surface Chemistry of High Quality Wurtzite and Kesterite Cu2ZnSnS4Nanocrystals Using Tin(II) 2-Ethylhexanoate as a New Tin Source

A novel synthesis method for the preparation of Cu2ZnSnS4 nanocrystals is presented using a liquid precursor of tin, namely tin(II) 2-ethylhexanoate, which yields small and nearly monodisperse NCs either in the kesterite or in the wurtzite phase depending on the sulfur source (elemental sulfur in oleylamine vs. dodecanethiol).
