Abstract

Here, we report the preparation and characterization of stable AgIn₅Te₈ (AITe) nanocrystals (NCs) and their respective AITe-ZnS and AITe-ZnSe alloys. A green route of synthesis is described by using an aqueous electrochemical method in a cavity cell. The elemental ratio modulation of the NCs was investigated to determine the ideal improvement of the structural and electronic properties. The AITe NCs presented an emission band at 889 nm and hypsochromic shifts when coated with ZnS and ZnSe seeds. Photothermal analyses point to theranostic applications.
