Trap-Programmable Ruddlesden-Popper Perovskite Nanocrystals for Persistent Optoelectronic Memory and Photonic Synapses. [PDF]
Adv Sci (Weinh)This work presents trap‐programmable Ruddlesden–Popper perovskite nanocrystals for ultralong‐lived optical memory and photonic synapses. Layer‐controlled octahedral distortion modulates trap depth and carrier‐storage kinetics, enabling persistent luminescence beyond 5000 s at room temperature.
