A High-resolution Patterning of Electroluminescent Quantum Dot Pixels via Photo-crosslinking

초록

The emergence of near-eye displays for an extended reality (XR) has promoted the development of high-resolution electroluminescence quantum dot (EL-QD) devices. Direct photo-lithography using photosensitive moieties is an effective technique for producing micrometer-sized patterns of colloidal quantum dots. Here, we fabricated red, green, and blue quantum dot patterns with a resolution of>4,500 pixels per inch using an azide-based photo-crosslinking method, which is a simple and applicable to a versatile patterning or integrating process. The effect of QD ligands and solvents on the electroluminescence characteristics and pattern fidelity of QD films during the patterning process was studied. © 2024, John Wiley and Sons Inc.
