Fig. 4From: Near-infrared emitting AgInTe2 and Zn-Ag-In-Te colloidal nanocrystalsTEM images of Zn-Ag-In-Te NCs with a Zn:Ag ratio of a 0.5:1 and b 1:1 from aliquots taken after 120 min of reaction. c Wavelength of the PL maximum as a function of reaction time for Zn-Ag-In-Te NCs with a Zn:Ag ratio of 0.5:1 (orange triangles) and 1:1 (purple crosses). All NCs were prepared at a reaction temperature of 170°CBack to article page
