“…The PL maxima are located at ≈385 and 395 nm, with full width at half maximum (FWHM) values of 54 and 52 nm and relatively small Stokes shifts of 85 and 93 nm for Rb 2 CuBr 3 and Rb 2 CuCl 3 , respectively. Usually, low‐dimensional (1D and 0D) metal halides materials emit strongly Stokes shifted spectra due to significant structural distortions in excited states . In contrast, our PL results on Rb 2 CuX 3 are notably different for several reasons.…”

The United States Department of Energy (DOE) projects an estimated energy cost savings of $630 billion from 2015 to 2035 if reliable solid-state lighting technologies can be developed and DOE goals are met. [1] For the cost-effective implementation of light-emitting diodes (LEDs), development of new inexpensive light emitters is an urgent need. Owing to their outstanding photophysical properties including tunable bandgaps and emission colors, high photoluminescent quantum yields (PLQY) and excellent color purity, metal halide perovskite LEDs (PeLEDs)

“…The L normally has ammonium cations that can react with the terminated [BX 6 ] 4− corner‐shared layer and fit the periphery of these octahedra. These RP‐type perovskites can be assembled into a bulk crystal or other nanostructures through the van der Waals interaction of each layer, keeping quantum confinement effects unchanged . In this section, we concentrate on the synthesis methods and corresponding applications of nanoplatelets based on 3D networks and partially discuss the 2D RP‐phase assembled bulk perovskites when referring to some optoelectronic applications.…”

“…[38][39][40] "Low-dimensional" perovskites refer to the perovskite compounds with at least one reduced dimension, in contrast to that with three unlimited extensions. [41][42][43][44][45] The term "low-dimensional" often leads to confusion due to its diverse meanings in different situations. In this review, we classify low-dimensional perovskites from two aspects: "material-level" and "structure-level" low dimensionalities.…”

“…No matter they are assembled into nanostructures or even bulk films, the inherent properties remain nearly unchanged relative to the basic blocks. [44][45][46][47][48][49][50] Differently, "structure-level" low-dimensional perovskites emphasize the final morphologies and commonly refer to those nanostructures of nanoplatelets/nanosheets, nanowires/nanorods, and nanocrystals ( Figure 1B). [51][52][53] Mostly, these "structure-level" low-dimensional perovskites are made up of the 3D networks of corner-sharing [BX 6 ] 4− octahedra, the same as that in bulk ABX 3 perovskites.…”

Low‐dimensional materials have pivotal significance in modern photonic, electronic, and optoelectronic areas due to their unique properties of the scale effect. Metal halide perovskites have revived in the optoelectronic fields recently, drawing intensive attention in photovoltaic devices, light‐emitting diodes, lasers, photodetectors, and so on. Compared to their three‐dimensional counterparts, the role of low‐dimensional perovskites is becoming crucial, requiring a comprehensive understanding and exploration unceasingly. In this review, we examine low‐dimensional perovskite of different forms and clarify various synthesis methods with morphological and dimensional control. Additionally, we also summarize potential optoelectronic applications based on their advantageous optical/electrical properties and enhanced mechanical integrity and stability. Finally, we propose a future perspective and possible developing directions in the exploration of novel perovskite‐derived materials, new physics, and promising applications.

“…By tuning the material combinations of organic and inorganic metal halides, formation of organic metal halide hybrids with different dimensionalities at the molecular level can be achieved. Determined by the nanostructures of the metal halide backbones in the corresponding crystalline bulk assemblies, molecular low‐dimensional organic metal halide hybrids are defined to be 2D, 1D, and 0D materials . The 1D family among them, exhibits prominent structural versatility.…”

Br 7 with a unique tubular structure, as shown in Figure 1. [3d] The single crystal contains parallel arrays of 1D lead bromide nanotubes with organic cations ionically bonded to the surfaces inside and out. Since the metal halide nanotubes are spatially isolated from each other, there is negligible inter-tubular interaction and band dispersion, so that the intrinsic properties of an individual nanotube can be manifested by its bulk assembly. This 1D organic metal halide hybrid have been reported to exhibits yellowish-white emission with exciton-exciton annihilation, and with good stability. [3d,4] Considering the vast functionalities of other nanotube materials, such as carbon nanotubes (CNTs), [5] we believed that this unique bulk assembly of 1D organic metal halide nanotubes could have multiple functionalities besides its intriguing optical properties.Microwave absorbing materials are important components for many military and civil applications, such as antiradar detection and wireless communications, [6] used in order to reduce the radar signature and electromagnetic interference of various equipment. To date, a variety types of materials have been ] etc. In this work, we first time investigate and report the microwave dielectric and magnetic properties and microwave absorption performance of the 1D organic metal halide hybrid (C 6 H 13 N 4 ) 3 Pb 2 Br 7 . The microwave absorption performance is analyzed in detail, in terms of the reflection loss peak frequency (f peak ), reflection loss peak value (RL peak ), the critical reflection loss peak width (Δf 10 ), and their relationships with the thickness of the absorber (d). Our study not only enriches the knowledge of organic metal halide hybrids, but also provides a potential new class of materials for microwave absorption.
