Soft-Electronic Quantum Dot Light-Emitting Diodes

We demonstrated a wearable red-green-blue (RGB) colloidal quantum dot light-emitting diode (QD LED) array with high resolution using a novel intaglio transfer printing technique (Nature Commun. 2015, 6, 7149). We also reported transparent QD LEDs with extremely high luminance and transmittance (Adv. Mater. 2018, 30, 1703279). We reported a novel device design and fabrication method using metal-based etch-stop layers and a laser-assisted patterning for 3D foldable QD LEDs (Nature Electronics 2021, 4, 671). Shape-tunable multiplexed phototransistor array was fabricated using an intrinsically stretchable and color-sensitive semiconducting nanocomposite consists of size-tuned quantum dots, blended in a semiconducting polymer within an elastomeric matrix (Nature Nanotech. 2022, 17, 849). We report novel material and device strategies for the intrinsically-stretchable quantum dot light-emitting diode (is-QLED) (Nature Photon. In revision). We reported on the design and synthesis of highly stable, photoluminescent, and catalytically active suprastructures of (CdSe)₁₃ nanoclusters (Nature Mater. 2021, 20, 650).
