Article Synopsis
- Colloidal quantum dot (QD) emitters have potential for next-gen displays, but current manufacturing methods lack precision and uniformity for large-scale applications.
- * Researchers introduced a selective electrophoretic deposition (SEPD) technique combined with photolithography, allowing for high-resolution, cost-effective QD patterning beyond 1,000 pixels-per-inch.
- * This method enables precise control over QD thickness and properties, improving efficiency and demonstrating its practical use for creating full-color QD displays and QLEDs suitable for commercial production.
We introduce stoichiometry control within both core and shell regions of InP/ZnSe/ZnS core/shell/shell quantum dots (QDs) to advance their properties drastically, approaching those of state-of-the-art CdSe-based QDs. The resulting QDs possess near-unity photoluminescence quantum yield, monoexponential decay dynamics, narrow line width, and nonblinking at a single-dot level. Quantum-dot light-emitting diodes (QLEDs) with the InP/ZnSe/ZnS core/shell/shell QDs as emitters exhibit a peak external quantum efficiency of 12.
