Composition-controlled optical fingerprints and anisotropy of self-trapped excitons in double perovskites

Simone Grillo, Offir Zachs Maishlos, Liya Koren +7

Double perovskites (DPs) offer a compositionally versatile platform for photocatalysis and optoelectronics, but their soft lattices favor strong exciton-phonon coupling and self-tr…
