Near-Infrared Emitting AgInTe2 and Zn-Ag-In-Te Colloidal Nanocrystals

Nanoscale Res Lett. 2015 Dec;10(1):951. doi: 10.1186/s11671-015-0951-y. Epub 2015 Jun 5.

Abstract

The synthesis of AgInTe2 nanocrystals emitting between 1095 and 1160 nm is presented. Evolution of the Ag:In:Te ratio shows progressive incorporation of In(3+) in Ag2Te, leading to the formation of orthorhombic AgInTe2. When zinc is added to the synthesis, the photoluminescence quantum yield reaches 3.4 %.
