In situ nanocrystallization on the perovskite film surface for enhanced light emission

Key Points

• The aim is to improve light emission in organic-inorganic hybrid perovskite films.
• Utilized phosphine oxide-based compounds to modify perovskite films
• Implemented in situ nanocrystallization technique on film surfaces
• Examined the effects on non-radiative recombination processes
• Significant enhancement in light emission observed
• Reduced non-radiative recombination rates were noted
• Improvement suggests potential for advanced optoelectric applications
