Coupling electromagnetic radiation with matter is promising to tailor optoelectronics properties of functional materials. Here, the authors demonstrate that internal fields induced by coherent lattice motions can be used to control transient excitoni

Abstract The zero‐dimensional Cs4PbBr6 perovskites are highly emissive materials that demonstrated an effective potential in light emitting applications. There is an on‐going debate regarding the origin of its strong and green photoluminescence,

We show that formamidinium lead bromide is unique among the halide perovskite crystals because its inorganic sub-lattice exhibits intrinsic local static disorder that co-exists with a well-defined average crystal structure. Our study combines THz-ran

Recent investigations of two-dimensional (2D) hybrid organic-inorganic halide perovskites (HHPs) indicate that their optical and electronic properties are dominated by strong coupling to thermal fluctuations. While the optical properties of 2D-HHPs h

Here we investigated how the alkylammonium length influences the optical and physical properties of organic–inorganic perovskite nanoparticles (NPs). The NPs were synthesized under ambient atmosphere. This synthesis led to the formation of luminesc

Due to the sizable refractive index of lead halide perovskites, reflectivity off their interface with air exceeds 15%. This has prompted a number of investigations into the prominence of photoreflective contributions to pump–probe data in these mat

Sub-10 fs resolution pump-probe experiments on methylammonium lead halide perovskite films are described. Initial response to photoexcitation is assigned to localized hot excitons which dissociate to free carriers. This is attested to by band integra
