Abstract
We report color-tunable light-emitting devices employing CdSe/ZnS quantum dots (QDs) blended into a polymer light-emitting electrochemical cell (LEC) architecture. This novel structure circumvents the charge-tunneling barrier of QDs to achieve bright, uniform, and highly voltage-independent electroluminescence, with nearly all emission generated by the QDs. By blending varying ratios of two QD materials that emit at different wavelengths, we demonstrate precise color control in a single layer device structure.
