The recent observation of broadband white-light emission from the inorganic sheets certain layered lead-bromide perovskites has instigated a multitude studies on this unusual phenomenon. However, vast majority bromide have flat (001) and display narrow photoluminescence at room temperature. A handful heavily distorted broad emission, but to date, there is no method predicting which will produce white light temperature prior screening different organic molecules that can template 2D...
Recent investigations into the effects of dimensional reduction on halide double perovskites have revealed an intriguing change in band structure when three-dimensional (3D) perovskite is reduced to a two-dimensional (2D) with inorganic sheets monolayer thickness (n = 1). The indirect bandgap 3D Cs2AgBiBr6 becomes direct n 1 whereas Cs2AgTlBr6 at limit. Here, we apply linear combination atomic orbitals approach uncover orbital basis for this symmetry transition reduction. We adapt our...
