Abstract
Lead halide perovskite nanocrystals (NCs) have emerged as highly promising candidates for next-generation optoelectronic devices due to their excellent optical and electronic properties.
In this work, we report a facile ambient-air synthesis of hybrid organic–inorganic perovskite NCs using a triple-ligand system. This approach enhances ink stability and photoluminescence through ligand-assisted surface passivation.
Partial substitution of cations resulted in increased PL intensity. The emission color was tunable via halide composition.
The fabricated perovskite films exhibited uniform morphology and bright green photoluminescence. When applied to light-emitting diode (LED) devices, the FA-doped CsPbBr₃ films demonstrated superior luminance compared to pristine CsPbBr₃.These results suggest that solution-processed, ligand-engineered perovskite NCs hold strong potential for high-definition display and solid-state lighting applications.
