Cu–In–Te and Ag–In–Te colloidal nanocrystals with tunable composition and size†
Abstract
We synthesize stable colloids of Cu–In–Te and Ag–In–Te nanocrystals using an amide-promoted technique, which enables independent size and composition control, and report the dependence of structural and optical properties on composition and size. Comparison to the synthesis of other ternary I–III–VI nanocrystals gives insight into the reaction mechanism and the generalizability of the amide-promote approach.
