Halide perovskite nanocrystals （NCs） with a general composi- tion of ABX3 （A = MA, FA or Cs, B = Ph, Sn; and X = Br, 1, CI） have been widely studied for photovoltaic applications. Recently, halide perovskites NCs based light-emitting diodes （LEDs） have also attracted significant attention because they have been regarded as the next-generation display technology [1 ]. However, we are still far from the commercialization of this type of materials due to their well-known instability problem. One of the possible routes to overcome the stability issues is to systematically investigate the new materials and find a more stable phase or composite.
