a, structure of LED based on PeNCs without and with passivation. Schematic illustrates that CP could passivate defects, in which the defects may trap carriers (e.g. holes, electrons), decrease exciton recombination, and hence degrade the device performances. b, Schematic and energy-level diagrams of the Ln³⁺ ion-doped CsPbCl₃ LED configuration. c, Simplified energy-level diagram of Ln³⁺ ion luminescence process and corresponding EL spectra for the LEDs based on these Ln³⁺ ions doped CsPbCl₃ PeNCs.
