Phosphonic acids aid composition adjustment in the synthesis of Cu_(2+x)Zn_(1−x)SnSe_(4−y) nanoparticles

Abstract

The functional properties of quaternary I_2–II–IV–VI_4 nanomaterials, with potential interest in various technological fields, are highly sensitive to compositional variations, which is a challenging parameter to adjust. Here we demonstrate the presence of phosphonic acids to aid controlling the reactivity of the II element monomer to be incorporated in quaternary Cu_2ZnSnSe_4 nanoparticles and thus to provide a more reliable way to adjust the final nanoparticle metal ratios. Furthermore, we demonstrate the composition control in such multivalence nanoparticles to allow modifying charge carrier concentrations in nanomaterials produced from the assembly of these building blocks.
