Breakthrough in Quantum Dot Surface Defect Repair: Enabling Ultra-High Efficiency and Long-Life QLEDs

<p>Steric hindrance of long-chain ligands leads to abundant unpassivated dangling bonds on quantum dots (QDs), which significantly impair the efficiency and operational stability of QD light-emitting diodes (QLEDs), especially in ultra-small pixel devices. Professors Fushan Li and Hailong Hu at Fuzhou University have pioneered a "ligand reconstruction" strategy using zirconium acetylacetonate (Zr(acac)4) to precisely repair the surface defects of QDs.</p> <p>The post <a href="https://www.semiconductor-digest.com/breakthrough-in-quantum-dot-surface-defect-repair-enabling-ultra-high-efficiency-and-long-life-qleds/">Breakthrough in Quantum Dot Surface Defect Repair: Enabling Ultra-High Efficiency and Long-Life QLEDs</a> appeared first on <a href="https://www.semiconductor-digest.com">Semiconductor Digest</a>.</p>
