Abstract

Stability is one of the most serious intrinsic limiting factors for the application of halide perovskites in optoelectronics. In this communication, we introduce the concept of space localization to tackle this problem by fixing the unstable organic methylamine cation using inorganic salts. The obtained luminescent CH₃NH₃PbBr₃/NaNO₃ nanocomposites exhibit enhanced stability against thermal and photo-degradations.
