Abstract:
Organic-inorganic metal halides exhibit excellent compositional flexibility. When an ideal perovskite structure is adopted, they have the general formula ABX3, where A+ can be an organic or inorganic cation, B 2+ is an inorganic cation and X- is a halide anion. By changing the A, B, and X sites, the crystal structure, electronic structure and band gap can be tuned for a variety of optoelectronic applications, such as solar cells, light-emitting diodes, and photodetectors. However, the toxicity of lead in these materials is undesirable for practical applications. Thus, lead-free organic-inorgan

Abstract:
Environmentally friendly lead-free metal halide scintillators have attracted significant research interest in recent years in the field of radiation detection due to their low toxicity and outstanding radioluminescent properties. However, enhancing the luminescence performance of lead-free metal halide scintillators and fabricating thin films that integrate high light output, high spatial resolution, and excellent compatibility with photodetectors remain major challenges. To address these issues, this study employs CsCuI as the scintillating material and introduces Terbium (Tb) doping to tune

Abstract:
Abstract Metal halide perovskites have recently been reported as excellent scintillators for X-ray detection. However, perovskite based scintillators are susceptible to moisture and oxygen atmosphere, such as the water solubility of CsPbBr3, and oxidation vulnerability of Sn2+, Cu+. The traditional metal halide scintillators (NaI: Tl, LaBr3, etc.) are also severely restricted by their high hygroscopicity. Here we report a new kind of lead free perovskite with excellent water and radiation stability, Rb2Sn1-x Te x Cl6. The equivalent doping of Te could break the in-phase bonding interaction bet

Abstract:
As derivatives of metal halide perovskite materials, low-dimensional metal halide materials have become important materials that have attracted much attention in recent years. As one branch, zinc-based metal halides have the potential for practical applications due to their lead-free, low-toxicity and high-stability characteristics. However, pure zinc-based metal halide materials are still limited by their poor optical properties and cannot achieve large-scale practical applications. Therefore, in this work, we report an organic–inorganic hybrid zero-dimensional zinc bromide, (TDMP)ZnBr4, usin

Abstract:
Lead-free Mn2+-based metal halide materials are now being considered as clean candidates for backlight displays and lights due to the d–d transition, diverse components, and environmental friendliness. Therefore, efficient and stable Mn2+-based metal halide phosphors are in great demand for practical applications. In this work, adopting the mixed-ligand strategy, a series of [(CH3)4N]2−x[(C2H5)4N]xMnCl4 phosphors were synthesized by mechanochemical process. With the increase molar ratio of (CH3)4N/(C2H5)4N, the phase of phosphors is transformed from orthorhombic to tetragonal. Compared to [(CH

In this thesis, the surface chemistry of different metal halide NCs were investigated. Two new synthesis approaches to produce LHP NCs were developed by employing phosphonic acids (either alkyl or oleyl PAs) as the sole surfactants. The NMR analysis of these samples indicated the steric binding state of PA. PA-capped NCs show near unity PLQY with uncommon truncated shape, and high stability against dilution. We also investigated the interaction between neutral ligands and LHP NCs. Among various neutral ligands, it was found out that oleyl PAs are able to strip a large fraction of original surf

Abstract The completion of wells using solids-laden fluids can impair the reservoir production and also damage the functioning of downhole completion tools, therefore completing wells with clear-brine fluids is the preferred alternative. Clear brines are typically halide or formate salt solutions in water, but they, too, have shortcomings. At lower temperatures or increased pressures, the salts in these fluids can crystallize causing potential well control concerns and/or costly operational disruptions.
