Reprecipitation synthesis of luminescent CH3NH3PbBr3/NaNO3 nanocomposites with enhanced stability

摘要

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 photodegradations.
