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 (<i>Nature Commun</i>. <b>2015</b>, 6, 7149).We also reported transparent QD LEDs with extremely high luminance and transmittance (<i>Adv. Mater</i>. <b>2018</b>, <i>30</i>, 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 (<i>Nature Electronics</i> <b>2021</b>, <i>4</i>, 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 (<i>Nature Nanotech.</i> <b>2022</b>, 17, 849). We report novel material and device strategies for the intrinsically-stretchable quantum dot light-emitting diode (<i>is</i>-QLED) (<i>Nature Photon.</i> In revision). We reported on the design and synthesis of highly stable, photoluminescent, and catalytically active suprastructures of (CdSe)₁₃ nanoclusters (<i>Nature Mater.</i> <b>2021</b>, <i>20</i>, 650).
