Double Double Cation Order in the High‐Pressure Perovskites MnRMnSbO₆ [PDF]

Angewandte Chemie International Edition, 2016
AbstractCation ordering in ABO3 perovskites adds to their chemical variety and can lead to properties such as ferrimagnetism and magnetoresistance in Sr2FeMoO6. Through high‐pressure and high‐temperature synthesis, a new type of “double double perovskite” structure has been discovered in the family MnRMnSbO6 (R=La, Pr, Nd, Sm).

Lead-free perovskite and double perovskite solar cells

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The toxicity and instability of lead-halide perovskite materials in the solar cells are yet demands must be resolved to vie to find alternatives of free lead-based halide perovskites and double perovskite materials. Here we report on the experimental synthesis of a new family of lead-free inorganic halide double perovskites ...
