Persistent Dopants and Phase Segregation in Organolead Mixed-Halide Perovskites
Organo lead mixed -ha l ide perovsk i t e s such as CH3NH3PbX3−aX′a (X, X′ = I, Br, Cl) are interesting semiconductors because of their low cost, high photovoltaic power conversion efficiencies, enhanced moisture stability, and band gap tunability. Using a combination of optical absorption spectroscopy, powder X-ray diffraction (XRD), and, for the first time, Pb solid state nuclear magnetic res...
متن کاملConfining metal-halide perovskites in nanoporous thin films
Controlling the size and shape of semiconducting nanocrystals advances nanoelectronics and photonics. Quantum-confined, inexpensive, solution-derived metal halide perovskites offer narrowband, color-pure emitters as integral parts of next-generation displays and optoelectronic devices. We use nanoporous silicon and alumina thin films as templates for the growth of perovskite nanocrystallites di...

متن کاملLead Halide Perovskites and Other Metal Halide Complexes As Inorganic Capping Ligands for Colloidal Nanocrystals
Lead halide perovskites (CH3NH3PbX3, where X = I, Br) and other metal halide complexes (MX(n), 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 reactions and the effect on the optical properties of IV-VI, II-VI, and III-V semiconductor nanocrystals. In...
متن کاملOptical Properties of All-inorganic Metal-halide Perovskites and Metal Chalcogenides Colloidal Nano-crystals
Colloidal nanocrystals (NCs) are of considerable interest due to their size-dependent optical and electronic properties, which allow their implementation in photovoltaic cells, light-emitting diodes, photo-detectors and more. Along with the development of the synthesis procedures, numerous investigations have explored the optical and electronic properties of different NCs, involving the study o...
