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.
