To realize blue emission-capable non-Cd I-III-VI quantum dots (QDs), we explore the synthesis of ternary Cu-Ga-S (CGS) QDs and subsequent quaternary Zn-Cu-Ga-S (ZCGS) via Zn alloying into a CGS host. The resulting ZCGS/ZnS core/shell QDs possess not only Zn content-dependent tunable emissions in the azure-to-blue range but also exceptional quantum yields of 78-83%.
