Multifunctional Biguanide Additive Stabilizes Chloride-Rich Quasi-2D Perovskites for Efficient and Stable Pure-Blue LEDs
{{output}}
Quasi-2D perovskites are emerging as promising materials for light-emitting applications due to their pronounced quantum confinement effects. Blue perovskite light-emitting diodes (PeLEDs) remain fundamentally challenging yet critically demanded for display ap... ...
