Light-emitting diodes fabricated using Ag-In-Ga-S/GaSx quantum dots that exhibit vivid green emission were investigated, along with their electroluminescence (EL) properties. Defect-related emission components in the EL spectrum were suppressed by treatment with Ga compounds, and the EL exhibited color purity comparable to the photoluminescence.
