51.1: Invited Paper: Stable Full Color Perovskite Nanocrystals for Display Application

Perovskite nanocrystals (PNCs) are emerging luminescent materials that are promisingfor display application owing to their excellent optical properties and easy processing. However, it is still challenging to achieve high stability for PNCs in lighting emitting devices because of their high sensitivity to air, heat and moisture. Here we summary the recent developments in making highly efficient and stable PNCs‐polymer nanocomposite by the strategies of in‐situ surface reaction and initiator‐free polymerization. We show the PNCs that are surface capped with more‐covalent ligands and robust polymer shell present extraordinary stability in the conditions of air, light, moisture, and polar solvents. The applications of the polymer composite in LED device fabrication and micro/nano manufacturing are discussed. Finally, the color performance of the nanocomposites is summarized with a prospect for nano/micro‐LED display applications.
