Hydrogen Bonding Denticity Governs Surface Modulation in Inorganic Perovskite Nanocrystals.
All-inorganic CsPbI3 perovskite nanocrystals (PNCs) have emerged as promising emitters for optoelectronic applications owing to their high color purity, tunable bandgap, and high photoluminescence quantum yield (PLQY). However, dynamic surface ligands, abundant trap states, and rapid halide ion migration limit their em...
