In Situ Fabrication of Halide Perovskite Nanocrystal‐Embedded Polymer Composite Films with Enhanced Photoluminescence for Display Backlights

A simple and versatile in situ fabrication of MAPbX3 nanocrystal-embedded polymer composite films is developed by controlling the crystallization process from precursor solutions. The composite films exhibit enhanced photoluminescence properties, improved stability, and excellent piezoelectric and mechanical properties. Applications of these composite films as color converters in liquid-crystal-display backlights are demonstrated, showing bright potential in display technology.
