Cu-In-Te and Ag-In-Te colloidal nanocrystals with tunable composition and size.

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.
