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.

Core Shell Structure

The exposed Se on QD surface causes non-radiative relaxations which results in a low PLQY. However, the PLQY was improved from less than 8.0% up to above 85.0% by adding tributyl phosphine which can terminate the dangling bonds of the Se.
