What is it about?
See my short YouTube talks on this and other research works by clicking on the link under 'Resources' on the right ➡️➡️ Here, we tune the bandgap of these emerging 'perovskite-inspired materials' (https://iopscience.iop.org/article/10.1088/1361-6528/abcf6d) through Bi/Sb alloying

Why is it important?
This is important as it provides a new way to tune the optical properties of these materials.
Perspectives
This work is interesting as we demonstrate that these double perovskites exhibit the same unusual bandgap bowing as observed in the Pb/Sn system
