Doping Up the Light: A Review of A/B-Site Doping in Metal Halide Perovskite Nanocrystals for Next-Generation LEDs.

101 − 103 According to Shi et al., 101 as shown in Figure 10 a, when Rb ions are doped into the perovskite emissive layer, the breakdown voltage of the PeLEDs shows an increasing trend (from 9.6 to 11 V) as the increasing concentration of Rb, which indicates that Rb doping can enhance the durability of PeLEDs device.
