Download or read book Hybrid Organic inorganic Halide Perovskite Single Crystals Directed by Phosphonium Cation templates written by Saja Abdulrahman A. Althobaiti and published by . This book was released on 2021 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inorganic/organic hybrid perovskites have emerged as synthetic materials that exhibit promising applications in optoelectronic devices. There is a wealth in choice of organic cations that can be used to create hybrid structures with different shape, size, polarizability, and electronegativity. Although perovskites with ammonium cations have been previously reported, a perovskite family with phosphonium cations has been less investigated. This study reports the synthesis, crystal, and characterization of the novel low-dimensional phosphonium-base organic-inorganic hybrid single crystal materials. First, the phosphonium bromide salts were reacted with the lead bromides and iodides towards creating a perovskite crystal. Further reactions of phosphonium salts with the transition metal halides were made to discover if variant perovskite structures will be obtained. On the basis of the single-crystal X-ray diffraction results carried out at room temperature, the reaction of lead(II) bromide and iodide with various phosphonium salts produced a charge-balanced network of PbBr3 and PbI3– fragments connecting in a face-sharing octahedral motif. However, the reaction of lead(II) chloride and lead(II) iodide with tetraphenylphosphonium bromide (TPPB = C24H20PBr) produced a [Pb3(Cl/Br)8]2- and a [Pb2I6]2-that is surrounded by (C24H20P+) molecules (organic part), featuring a one-dimensional (1D) double chines and zero-dimensional (0D) structure, respectively. We note the increased cation size causes greater separation of charges, which tears apart the linked metal anion chains and lowers dimensionality; a separate effect was the formation of a new plumbate ion [Pb3(Cl/Br)8]2– where a Pb-phenyl interaction from a cation replaces an expected Pb-halogen bond. These phosphonium-templated haloplumbates were found to possess semiconducting properties, as suggested by the results of UV-Vis. Four novel crystal structures were isolated from reactions of tetraphenylphosphonium salt with zinc(II), cadmium(II), cobalt(II) and copper(II) chloride, each of them producing a unique geometry. Reacting TPPB with ZnCl2, (C24H20P)[ZnCl3(C3H7NO)] results in one (C24H20P+) cation and one [ZnCl3(DMF)] anion (DMF is dimethylformamide). In the anion, the zinc atom is tetrahedrally coordinated by a DMF ligand via the O atom and by three terminal Cl atoms. However, a different structure forms using TPPB with CdCl2, in which the CdX4 ion has a mixture of Cl and Br in a disordered state. As a result of the larger TPP cation, the TPP cation was found to break the -Cu-Cu-Cu-Cu- infinite chain and form dimers in which the smaller Cl atoms are bridging in the middle and the Br atoms are occupying the outer position. Photoluminescence investigation for (C24H20P)2Pb3(Cl/Br)8, zinc and cadmium components reveals a strong emission in the green region at 310 and 350 nm excitation wavelengths, respectively.

Available in PDF, EPUB and Kindle. Book excerpt: Perovskite is a well-known structure with the chemical formula ABX3, where A and B are cations coordinated with 12 and 6 anions, respectively, and X is an anion. When a halogen anion is used, the monovalent A and divalent B cations can be stabilized with respect to a tolerance factor ranging from ~0.8 to 1. Since the first report on ~10% efficiency and long-term stability of solid-state perovskite solar cells (PSCs) in 2012 and two subsequent seed reports on perovskite-sensitized solar cells in 2009 and 2011, PSCs have received increasing attention. The power conversion efficiency of PSCs was certified to be more than 25% in 2020, surpassing thin-film solar cell technologies. Methylammonium or formamidinium organic ion–based lead iodide perovskite has been used for high-efficiency PSCs. The first report on solid-state PSCs triggered perovskite photovoltaics, leading to more than 23,000 publications as of October 2021. In addition, halide perovskite has shown excellent performance when applied to light-emitting diodes (LEDs), photodetectors, and resistive memory, indicating that halide perovskite is multifunctional. This book explains the electro-optical and ferroelectric properties of perovskite and details the recent progress in scalable and tandem PSCs as well as perovskite LEDs and resistive memory. It is a useful textbook and self-help study guide for advanced undergraduate- and graduate-level students of materials science and engineering, chemistry, chemical engineering, and nanotechnology; for researchers in photovoltaics, LEDs, resistive memory, and perovskite-related opto-electronics; and for general readers who wish to gain knowledge about halide perovskite.

Download or read book The Optoelectronic Diversity of Layered Halide Perovskites written by Matthew David Smith and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The path towards emergent photophysics and new technologically desirable physical properties lies through synthesis of new materials. A powerful framework for developing such materials is the idea of hybrids, which contain both organic and inorganic components in a single chemical compound. These two building blocks each offer advantages compared to the other. The ability to design organic molecules with exact precision over atomic connectivity and elemental specificity is unmatched, while inorganic building units contribute increased robustness and intriguing optoelectronic properties. Additionally, the differing reactivities and stabilities of these components dictates simple and mild synthetic conditions such as solution-state self-assembly, allowing easy access to a diverse phase space of possible materials. I have explored how organic-inorganic hybrid materials contain both striking similarities and drastic departures from the optoelectronic properties of their separate components, particularly evident in the family of layered lead-halide hybrids. Much of my focus centers on understanding and controlling the behavior of excitons in the inorganic layers of the two-dimensional lead-halide perovskites. Using a combination of in situ optical spectroscopy and X-ray diffraction techniques, I demonstrated how reversible intercalation of polarizable species such as the molecular dihalogens, such as iodine, can tune the degree of electronic confinement without altering the structure of the inorganic layers in which excitons are confined. More reactive halogens react with the perovskite to perform unusual chemistry with both the organic and inorganic layers. Room-temperature white-light photoluminescence is a rare phenomenon exhibited by certain layered lead-halide perovskites. I initially helped elucidate the photoluminescence mechanism, which I ascribed to the radiative recombination of self-trapped excitons. I further demonstrated that this broad emission is not restricted to a few members of the halide perovskite family, but rather is common to all layered lead-chloride and lead-bromide perovskites, although this emission is highly temperature dependent. With variable-temperature photoluminescence and single-crystal X-ray diffraction, I established correlations between the propensity to exhibit broad photoluminescence at a given temperature and particular octahedral tilts of the lead-bromide octahedra, and provided further support for the self-trapped exciton hypothesis. With additional both static and time-resolved temperature-dependent optical spectroscopies, I found that self-trapped excitons are pervasive in the lead-bromide perovskites, even when the broad photoluminescence is not visible, suggesting a persistent pathway for non-radiative recombination that limits quantum efficiency. Finally, I extended the phenomenon of broadband photoluminescence beyond the layered perovskites to the class of lead-halide hybrids generally. I synthesized and characterized both layered and zero-dimensional lead-bromide hybrids templated by sulfonium-based cations that exhibit room-temperature broad red emission.
