Synthesis and electroluminescence of novel white fluorescence quantum dots based on a Zn–Ga–S host

Author affiliations

Abstract

White-light-emitting Ag, Mn: Zn–Ga–S/ZnS quantum dots (QDs) with a gratifying photoluminescence (PL) quantum yield (QY) of up to 90% were prepared, and shown to be ultra-stable, maintaining a high PL intensity at 300 °C or for 32 h of UV illumination. These QDs were employed in a white QD-LED displaying a color rendering index (CRI) of 72 and maximum current efficiency of 0.22 cd A−1.
