The Creation

In this study, we report the creation of heterostructured alloy core/shell Ag-In-Zn-S (AIZS)/ZnS quantum dots (QDs) by sequential core-forming, alloying and shelling processes and the fabrication of color-tunable QD light-emitting diodes (QLEDs) with a standard device architecture.

Information Displays

Flexible information displays hold great promise for future optoelectronic applications. Herein, we report the fabrication of an efficient flexible white quantum dot (QD) light-emitting diode (QLED) with mixed red, green and blue QDs as emitters via an all-solution process. The resulting flexible QLED with a pure white emission shows high current efficiency of 10.5 cd A−1.

Passivating Layer

The interactions between QDs and s-NiO can be largely suppressed through introducing a ultrathin Al2O3passivating layer. This highest current efficiency (external quantum efficiency) of 34.1 cd A−1(8.1%) is achieved.
