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 %.
