Lead halide perovskites have exhibited excellent performance in solar cells, LEDs and detectors. Thermal properties of perovskites, such as heat capacity and thermal conductivity, have rarely been studied and corresponding devices have barely been explored. Considering the high absorption coefficient (10~...
Lead halide perovskites have recently emerged as attractive optoelectronic semiconductors considering their large absorption coefficient, low defect density, long carrier lifetime, and convenient fabrication process1,2,3. These properties benefit the excellent device performance in solar cells4,5, light-emit...
Pb-halide perovskites’ photovoltaic performance perishes over moisture28,29, impeding the wide commercial application of such materials as solar cells. The stability is quite distinct if perovskites are to be applied to organic synthesis in which more critical parameters may influence the stability of ...

Lead halide perovskites (CH3NH3PbX3, where X = I, Br) and other metal halide complexes (MXn, where M = Pb, Cd, In, Zn, Fe, Bi, Sb) have been studied as inorganic capping ligands for colloidal nanocrystals. We present the methodology for the surface functionalization via ligand-exchange...
The recent meteoric rise in the field of photovoltaics with the discovery of highly efficient solar-cell devices is inspired by solution-processed organic-inorganic lead halide perovskites that exhibit unprecedented light-to-electricity conversion efficiencies. The stunning performance of perovskites is attri...

Lead halide perovskites based microlasers have recently shown their potential in nanophotonics. However, up to now, all of the perovskite microlasers are static and cannot be dynamically tuned in use. Herein, we demonstrate a robust mechanism to realize the all-optical control of perovskite microlaser...
Lead halide perovskites (LHPs) in the form of nanometre-sized colloidal crystals, or nanocrystals (NCs), have attracted the attention of diverse materials scientists due to their unique optical versatility, high photoluminescence quantum yields and facile synthesis. LHP NCs have a 'soft' and predomi...
We provide a direct time domain view of large polaron formation in single-crystal lead bromide perovskites CH3NH3PbBr3and CsPbBr3. We found that large polaron forms predominantly from the deformation of the PbBr3−frameworks, irrespective of the cation type. The difference lies in the polaron ...
