Dual P=O Groups Additive Synergistic Anti-Solvent Enables Efficient and Stable Quasi-2D Red Perovskite LEDs

Quasi-two-dimensional (quasi-2D) mixed iodine/bromine halides perovskites are promising emitters for cost-effective, high-efficiency red perovskite light-emitting diodes (PeLEDs). But mixed-halide perovskites suffer from poor film quality and pronounced non-radiative losses, which...
