Dynamic Lone Pair Expression‐Driven Strong Light Emission in a Zero‐Dimensional Ge(II)‐Based Perovskite
Metal halide perovskites derive their remarkable optoelectronic properties from the combined effects of strong electron‐phonon coupling, exciton localization, and the dynamic stereochemical activity of ns2 lone pairs. However, Ge (II)‐based perovskites typically exhibit static lone‐pair expression (LPE) and pronounced...
