Intrinsic doping limit and defect-assisted luminescence in Cs4PbBr6

Cs4PbBr6 is a member of the extended halide perovskite family that is built from isolated (zero-dimensional) PbBr64− octahedra with Cs+ counter ions. The material exhibits anomalous optoelectronic properties: optical absorption and weak emission in the deep ultraviolet (310–375 nm) with efficient lu...
