High‐Quality γ‐CsPbI3 Cuboid Crystallites Grown by Amorphous‐Complex Conversion for Efficient and Bright Deep‐Red Light‐Emitting Diodes

Inorganic CsPbI3 perovskite has great potential to fabricate deep‐red light‐emitting diodes (LEDs) owing to excellent color purity, thermal stability, and carrier mobility. However, fabricating high‐quality CsPbI3 thin films for high‐performance LEDs remains challenging. While it is demonstrated tha...
