New Variants of (110)‐Oriented Layered Lead Bromide Perovskites, Templated by Formamidinium or Pyrazolium
نویسندگان
چکیده
Four new hybrid lead(II) halide perovskites, γ-(FA)2PbBr4, (FA)1.5(AA)0.5PbBr4, (PY)(GA)PbBr4 and (PY)(TZ)PbBr4 ((FA)=formamidinium, (AA)=acetamidinium, (PY)=pyrazolium, (GA)=guanidinium (TZ)=1,2,3-triazolium), adopt (110)-oriented layered perovskite structures. While (PY) is found to template the formation of ‘conventional’ structure types (i. e. containing staggered [PbBr4]∞ layers), (FA) shown facilitate much less common variants based 3 : 1 ordering interlayer species or 3×2 step-like corrugation perovskite-like layers themselves.

Dismantling the “Red Wall” of Colloidal Perovskites: Highly Luminescent Formamidinium and Formamidinium–Cesium Lead Iodide Nanocrystals
Colloidal nanocrystals (NCs) of APbX3-type lead halide perovskites [A = Cs+, CH3NH3+ (methylammonium or MA+) or CH(NH2)2+ (formamidinium or FA+); X = Cl-, Br-, I-] have recently emerged as highly versatile photonic sources for applications ranging from simple photoluminescence down-conversion (e.g., for display backlighting) to light-emitting diodes. From the perspective of spectral coverage, a...
متن کاملHigh brightness formamidinium lead bromide perovskite nanocrystal light emitting devices
Formamidinium lead halide (FAPbX3) has attracted greater attention and is more prominent recently in photovoltaic devices due to its broad absorption and higher thermal stability in comparison to more popular methylammonium lead halide MAPbX3. Herein, a simple and highly reproducible room temperature synthesis of device grade high quality formamidinium lead bromide CH(NH2)2PbBr3 (FAPbBr3) collo...
متن کاملRetrograde solubility of formamidinium and methylammonium lead halide perovskites enabling rapid single crystal growth.
Here we show the retrograde solubility of various hybrid perovskites through the correct choice of solvent(s) and report their solubility curves. Retrograde solubility enables to develop inverse temperature crystallization of FAPbX3 (FA = HC(NH2)2(+), X = Br(-)/I(-)). FAPbI3 crystals exhibit a 1.4 eV bandgap--considerably narrower than their polycrystalline counterparts.
متن کاملMonodisperse Formamidinium Lead Bromide Nanocrystals with Bright and Stable Green Photoluminescence
Bright green emitters with adjustable photoluminescence (PL) maxima in the range of 530-535 nm and full-width at half-maxima (fwhm) of <25 nm are particularly desirable for applications in television displays and related technologies. Toward this goal, we have developed a facile synthesis of highly monodisperse, cubic-shaped formamidinium lead bromide nanocrystals (FAPbBr3 NCs) with perovskite ...
متن کاملEfficient Planar Heterojunction Perovskite Solar Cells Based on Formamidinium Lead Bromide.
The development of medium-bandgap solar cell absorber materials is of interest for the design of devices such as tandem solar cells and building-integrated photovoltaics. The recently developed perovskite solar cells can be suitable candidates for these applications. At present, wide bandgap alkylammonium lead bromide perovskite absorbers require a high-temperature sintered mesoporous TiO2 phot...
