“…Low-dimensional structures, especially one-dimensional (1D) and two-dimensional (2D) structures, are also anisotropic atomic structures that could produce interesting anisotropies, such as anisotropic electronic structure, anisotropic carrier transport, and birefringence. − Recently, examples of low-dimensional perovskite materials have shown linear dichroism behaviors and outstanding anisotropic properties and exhibited more promising applications in polarized luminescence, polarized photon detection, and optical modulation. − As is known, the large single crystals have a minimal number of grain boundaries and fewer structural defects and therefore usually lead to enhanced performance. , Several 2D hybrid perovskite single crystals have been synthesized recently, showing excellent anisotropic photonic performance. , Recently, Zhang et al reported centimeter-sized 1D perovskite ( n -propylammonium)(methylammonium)SbBr 5 single crystals with excellent linear dichroic anisotropy . However, reports of large 1D perovskite single crystals have been limited, and the corresponding anisotropic property has therefore also not been demonstrated.…”

Low-dimensional hybrid halide perovskite materials with self-trapped exciton (STE) emissions and anisotropic properties are highly attractive for their great potential in many applications. However, to date, reports on large one-dimensional (1D) perovskite single crystals have been limited. Here, centimeter-sized 1D single crystals of trimethylammonium lead iodide (TMAPbI 3 ) with typical STE emission are synthesized by an antisolvent vaporassisted crystallization method. Thermal quenching and antiquenching with a high relative sensitivity of photoluminescence (PL) are observed and studied via temperature-dependent photoluminescence spectroscopy. Further analysis indicates that the temperature-dependent PL behaviors are influenced by the self-trapping of the free exciton and the migrations between self-trapped excitons and intermediate nonradiative states. The TMAPbI 3 single crystal also exhibits a linearly polarized emission and a large birefringence that is higher than those of commercial birefringent crystals. This 1D perovskite with high structural anisotropy has promise for applications in versatile optical-and luminescence-related fields.

of polarization states: i) Natural light, the vibrational plane of which is not fixed. The electric vectors of natural light are axisymmetric, evenly distributed in all directions and synchronously vibrating. ii) Complete polarized light can be subdivided into linearly polarized light, elliptically polarized light, and circularly polarized light. Linearly polarized light has a fixed vibrational plane. The vibrational track of its electric vector is a straight line during propagation. Elliptically polarized light, similarly, the terminal trajectory that the electric vector vibrates is an ellipse. The plane of the ellipse is perpendicular to the propagative direction of light. And the electric vector rotates constantly, the magnitude and direction of which change regularly with time. When facing the direction light propagates, if the end of the electric vector travels counterclockwise, it is a right-handed circular polarization state; if clockwise, it is a left-handed circular polarization state. Circularly polarized light is a special case of elliptically polarized light. iii) Partially polarized light, the vibration of the electric vector has a comparative advantage in a certain direction. Simply, it is the superposition of natural light and complete polarized light. Because of that common characteristic of light, the polarization state of light provides a new degree of freedom in detection and application. [18,19] Early studies of the polarization-sensitive photodetectors mainly focus on the macroscopic anisotropy, which requires complex technologies for the patterning and aligning process. [20][21][22] Anisotropic low-dimensional materials have low-symmetry crystal structures including orthorhombic, monoclinic, and triclinic so that they have intrinsic anisotropic properties [23][24][25] obtaining highly polarization sensitivity for photodetectors. [26,27] Fortunately, low-dimensional materials are emerging due to their large families, [28][29][30][31][32] fascinating photo electric characteristics, [28,[32][33][34] and naturally microscopic anisotropy among most of them. [23] From early on, the pioneering work has been done on BP-based polarization-sensitive photodetectors, which advance the development of anisotropic systems in this application. [35] According to the diversified evolution of element types, apart from black phosphorus, [36][37][38][39][40] some monoelemental 2D materials with anisotropy like black arsenic, [41,42] antimonene, [43,44] borophene, [45,46] and tellurene [47,48] have been discovered and studied. Meanwhile, a mass of anisotropic binaries have sprung up typically including

When the exciton level of the inorganic layer is located above the singlet level of organic spacers, the luminescence of 2D perovskites is mainly dominated by the OC [108,109] PV [110,111] MG [112] FE [113,114] CO [115] PZE [116] 1D -LM [17,117] FE [118,119] FM [120] 0D [121,122] PV [123] FE [124] a) E g (bandgap), e (electronic effective mass), m h (hole effective mass), E b (exciton binding energy), optoelectronic (OC), photovoltaic (PV), magnetic (MG), ferroelectric (FE), chiral optics (CO), piezoelectricity (PZE), luminescence (LM), ferromagnetism (FM).

Lead halide perovskites are regarded as potential successor of traditional perovskites, due to their variable structures and excellent optoelectronic properties. However, its large‐scale commercialization is impeded by the inherent instability and toxicity. In this regard, lead‐free low‐dimensional perovskites (LFLDPs) have emerged as promising alternatives to the traditional 3D components, due to their structural tunability and environmental friendliness and stability. The structure–property characteristics of LFLDPs endow them with a unique combination of optoelectronic efficiency and versatile functionality, which has led to their impressive employment in the optoelectronic devices. In this perspective, a brief description of recent progress on the various LFLDPs, and especially from theoretical perspective, is presented. First, the general types of LFLDPs are introduced and the metal elements that have been used to date in the exploitation of LFLDPs are collected. This is followed by a discussion of fundamental understanding of the structure–property relationship for different dimensional perovskites in the view of connectivity and element composition. Finally, luminescence mechanism of relevant LFLDPs and the key frontiers and challenges for further developing LFLDP materials is discussed.
