The recent success of solar cells has witnessed the emergence of metal halide perovsldtes as an important class of optoelectronic materials. Even with the record efficiency and inspiring performance, lead based perovskites are criticized for its toxicity, raising concerns about the environmental pollution. The reported divalent and heterovalent metal substitution for Pb indicates unfavorable performance. The lead-containing perovskite exhibits the outstanding activity compared to lead-free analogues. It is speculated that the perovskite with mixed-metal cation is expected to enable the fabrication of efficient device and partially alleviate toxicity. For this reason, herein, we present the first synthesis of perovskite nanocrystals based on mixed-metal cation, and demonstrate the implementation of mixed-metal cation perovskite nanocrystals into LEDs for the first time.
