Narrow‑band red emission from engineered copper chalcogenide quantum dots. (IMAGE)
Caption
Normalized photoluminescence spectrum of the CIGS‑ZIS‑ZnS quantum dots in solution. The emission peak at 632 nm with a full width at half maximum (FWHM) of 78 nm confirms the successful suppression of defect‑related broad emission through the ZnInS₂ interfacial layer, achieving high color purity while maintaining a photoluminescence quantum yield of 95.3%.
