SnI4 is Iron carbide structured and crystallizes in the cubic P-43m space group. The structure is zero-dimensional and consists of one stannic iodide molecule. Sn4+ is bonded in a tetrahedral …

2021年5月14日 · We show that SnI 4, a product of the oxygen-induced degradation of tin perovskite, quickly evolves into iodine via the combined action of moisture and oxygen. We …

2024年3月1日 · Combining high-pressure XRD, absorption spectroscopy, and theoretical calculations, we propose that the improved photoelectric properties of SnI 4 is associated with …

2022年11月1日 · X-ray diffraction analysis revealed the formation of SnI 4 thin films which crystallized in cubic Pa-3 structure and all samples were preferentially oriented along the (222) …

SnI4 is Iron carbide-like structured and crystallizes in the cubic Pa-3 space group. The structure is zero-dimensional and consists of eight stannic iodide molecules. Sn4+ is bonded in a …

XRD patterns of films with 1.5-5 mol % Mn 2+ doping revealed perovskite features similar to that of the pristine Cs 2 SnI 6 film, indicating that negligible structural changes were induced by the...

2022年1月17日 · The crystal structure of the as-fabricated perovskites was identified by applying X-ray diffraction (XRD) characterization. As shown in Figure 1a , the XRD patterns show …

2017年12月1日 · In this presentation we will illustrate recent XAS results on SnI4, both at the Sn and I K edge combined with XRD. The EXAFS data have been fitted using the Reverse Monte …

Lead-free PEA 2 SnI 4-based perovskite LEDs are successfully inkjet-printed on rigid and flexible substrates. Red-emitting devices (λ max = 633 nm) exhibit, under ambient conditions, a …

Standard and reverse Monte Carlo extended x-ray absorption fine structure (EXAFS) refinements confirm that the penta atomic SnI4 structural unit tetrahedron is a fundamental structural unit …
