Puntos clave

To investigate how acetate interlayers can reduce nonradiative recombination in blue perovskite LEDs.
Analyzed crystallization kinetics during spin-coating of quasi-2D blue perovskite precursors.
Examined film morphology and grain growth.
Evaluated the impact of interfacial defects on LED performance.
Found that acetate interlayer significantly decreased interfacial defects.
Observed improved film morphology and uniform grain growth.
Demonstrated enhanced performance of blue perovskite LEDs.

Resumen

Rapid crystallization kinetics of quasi-2D blue perovskite precursors during spin-coating leads to uneven grain growth, porous film morphology, and increased interfacial defects, which exacerbates nonradiative recombination at the bottom of...
