(a) XRD patterns of pure PbBr 2 or complex formed in different solvents. The data are obtained by sequentially dissolving PbBr 2 into the DMF/DMSO solvent, evaporating the solvent, and...

We describe an innovative method to fabricate the one-dimensional (1D) microrods of lead bromide (PbBr2). The microrods possess unique structural and morphological properties. XRD, FESEM and...

2020年2月8日 · We describe an innovative method to fabricate the one-dimensional (1D) microrods of lead bromide (PbBr2). The microrods possess unique structural and morphological properties. XRD, FESEM and HRTEM analysis exhibited a well-ordered growth and a crack-free arrangement of the microcrystals in rod shapes.

CsPbI2Br perovskite, prized for its superb stability toward light soaking and thermal aging, has received a great deal of atte... [...] Tin (Sn)–lead (Pb) mixed perovskite solar cells (PSCs) stand...

2024年6月15日 · To find out the key factors determining the film quality in the proposed CINIT method, SEM and X-ray diffraction (XRD) were adopted to investigate the morphology and crystal phase of intermediate films prepared with different CsBr to PbBr 2 ratios (marked as Cs/Pb), where the concentration of PbBr 2 is fixed at 1.5 mol L −1.

2021年5月31日 · The structural analysis took place through X-ray diffraction experiments (XRD), in an X’Pert Pro PANalytical equipment, under an operating voltage of 40 kV, a current of 30 mA and Cu Kα radiation with wavelength λ = 1.5302 Å, sweeping a 2θ angle between 10° and 50°. In order to study the surface morphology of samples, scanning electron ...

We describe an innovative method to fabricate the one-dimensional (1D) microrods of lead bromide (PbBr2). The micro-rods possess unique structural and morphological properties. XRD, FESEM and HRTEM analysis exhibited a well-ordered growth and a crack-free arrangement of the microcrystals in rod shapes.

PbBr2 is Rutile structured and crystallizes in the tetragonal P4_2/mnm space group. The structure is three-dimensional. Pb2+ is bonded to six equivalent Br1- atoms to form a mixture of edge and corner-sharing PbBr6 octahedra. The corner-sharing octahedral tilt angles are 49°. All Pb–Br bond lengths are 3.06 Å.

2023年1月10日 · Structural features play key role in determining the strength of the materials and these details can be obtained from the XRD, FTIR, Raman spectra, etc. Hence the authors studied the FTIR and Raman spectral features of PbBr2 -CdO-Bi 2 O 3 -B 2 O 3 glasses to investigate the structural changes in the glasses. 2. Experimental analysis.
