Aqueous synthesis of photoluminescence enhanced CuInS2/ZnS quantum dots via the facile hot injection growth of AgInS2 interlayer
Source abstract
Abstract
In this study, the hot injection of Ag ions to enhance the PL performance of aqueous-phase CuInS 2 /ZnS quantum dots (QDs) via the formation of AgInS 2 interlayer is first developed. Different amount of Ag doping by hot injection realizes the precise tuning of the peak wavelength from 649 nm to 684 nm, while the photoluminescence quantum yield is also improved from 14.79% to 26.8% due to the formation of the AgInS 2 interlayer on the surface of CuInS 2 QDs. The results of various characterizations demonstrate the formation of AgInS 2 interlayer and explain the enhanced PL performance of CuInS 2 QDs. This will expand the understanding of the PL enhancement of the aqueous-phase CuInS 2/ZnS QDs and solidify the foundation for subsequent practical research to further realize the potential of aqueous CuInS 2 QDs.
