Template-guided sodium intercalation enables phase-pure alkali metal-based ternary chalcogenides nanocrystals

Abstract

Alkali metal-based ternary chalcogenides are promising materials which remain synthetically underexplored. Here, a template-based strategy enables synthesis of colloidal NaInS₂ and NaIn₃Se₅ nanocrystals. Mechanistic insights reveal sodium intercalation as a predictive route to phase-pure ABZ nanocrystals.
