Abstract
The present invention relates to aqueous processes to make metal chalcogenide nanoparticles that are useful precursors to copper zinc tin sulfide/selenide and copper tin sulfide/selenide. In addition, this invention provides processes for preparing crystalline particles from the metal chalcogenide nanoparticles, as well as processes for preparing inks from both the metal chalcogenide nanoparticles and the crystalline particles.
