Photoluminescence of Sn2+–I−-mixed molecular perovskites

Abstract

Novel three-dimensional molecular perovskites with the general formula ABX₃ (A = N-methyl-N′-diazabicyclo[2.2.2]octonium, B = NH₄⁺, X = BF₄⁻ or ReO₄⁻) were constructed. These molecular perovskites can act as hosts of phosphors like Sn²⁺ to emit intense light under the excitation of UV light.
