Abstract

Thermochromic lead-free double perovskites Cs2AgBiBr6 are demonstrated. The anharmonic fluctuations and associated strong electron-phonon coupling, combined with the spin-orbit coupling effect, are responsible for the thermochromism. Our findings provide new insights for the development of optoelectronic devices based on double perovskites.
