Excited to share our new work published in Chemical Science where we have cracked a new way to make perovskite nanocrystals shine even brighter! By doping CsPbCl₃ nanocrystals with a little bit of Ni²⁺ we have enhanced their photoluminescence using a phenomenon called vibrationally assisted delayed fluorescence (VADF) — making light emission smarter and stronger!
This could be a game-changer for next-gen LEDs, lasers, and solar tech!
