The pressure-induced bandgap evolution of double perovskite Cs2AgBiBr6 nanocrystals is highly related to the orbital interactions, associated with the tilting and distortion of [AgBr6]5− and [BiBr6]3− octahedra under pressure.

Upward Deviation

The halide double perovskite solid solution Cs2AgBiBr6−xClx has been investigated and found to exhibit a band gap that increases from 2.2 eV to 2.8 eV as the Cl− content increases, with an upward deviation from Vegard's law when x > 5.
