摘要

We propose a fast and low-temperature method to synthesize CuInS2/ZnS quantum dots (CIS/ZnS QDs) using polyetheramine (D400) as solvent. It was found that the CIS/ZnS QDs synthesized at 140 °C exhibited a broad photoluminescence (PL) emission bandwidth (i.e., 135 nm) and a small PL blueshifted (i.e., 20 nm) as we coated the ZnS shells onto the CIS cores. Compared with the conventional GaN-based white light-emitting diodes with phosphor only, it was found that we could improve color rendering index and correlated color temperature by adding the CIS/ZnS QDs.
