None:
More efficient and stable blue LEDs are essential for achieving the full potential of halide perovskite-based displays, but defect formation and ion migration limit both external quantum efficiency and lifetime of these devices. Now, a multifunctional fluorinated ligand is shown to mitigate both factors, dramatically enhancing brightness, efficiency and lifetime.
