Lead-free double perovskites, A<sub>2</sub> M<sup>+</sup> M<sup>'3+</sup> X<sub>6</sub> , are considered as promising alternatives to lead-halide perovskites, in optoelectronics applications. Although iodide (I) and bromide (Br) mixing is a versatile tool for bandgap tuning in lead perovskites, similar mixed I/Br double perovskite films have not been reported in double perovskites, which may be due to the large activation energy for ion migration. In this work, mixed Br/I double perovskites were ...[more]
