“…It is found that 1 shows an absorption edge at ∼400 nm (Figure 6), which directly indicates compound 1 is an indirect band gap semiconductor. The absorption edge is comparable with another hybrid perovskite of C 12 H 28 Br 4 N 4 Pb, [23] (γ‐methoxy propyl amine) 2 PbBr 4 [24] …”

“…The absorption edge is comparable with another hybrid perovskite of C 12 H 28 Br 4 N 4 Pb, [23] (γ-methoxy propyl amine) 2 PbBr 4 . [24] According Tauc equation, the band gap of 1 was estimated to 2.78 eV (intercept value of a plot of (F(R 1 )hv) 1/2 -Energy; inset at Figure 7). The band gap is smaller than that of the based on acyclic cations phase transition material (C 6 H 14 N) 2 PbBr 4 (3.05 eV), [25] which could be used in high power/ efficiency optoelectronic devices.…”

Cyclic organic amines are emerging as excellent building blocks to assemble organic–inorganic hybrid phase transition materials due to their flexible cyclic structure. Here, we have assembled a 1D organic‐inorganic hybrid dielectric material C5H6NOPbBr3 (1) by alloying the cyclic organic amine 3‐hydroxypyridine. 1 displays a remarkable switchable dielectric response induced by an order‐disorder transformation of the organic moiety, this transformation behaviour is confirmed by DSC and Hirshfeld surface measurements. More interestingly, 1 has a narrowband emission (FWHM=4.64 nm) at 590 nm; FWHM is a major quality figure for narrowband photodetectors. In addition, 1 exhibits semiconducting properties with an indirect bandgap of 2.78 eV by the analysis of the UV‐Vis absorption results.

“…[99][100] The corrugated (110)-family of lead halide perovskites has been extensively pursued due to the associated, characteristic broadband emission where the majority of the materials are (110)-lead bromide perovskites (Table 2). [92,100,[119][120][121][122][123][124][125][126][127][128][129][130][131][132][133][134][135] There has been great pursuance in defining structural prerequisites for the targeted and rational design of (110)-orientated perovskites. Initially, (API)PbBr 4 can be tracked as the first (110)lead bromide perovskite reporting broadband emission, in which API = 1-(3-Aminopropyl)imidazole.…”

Bulk, 2D hybrid lead bromide perovskites comprise a robust family of halide perovskites with a rich structural and photophysical chemistry witnessed thus far. In an attempt to boost focus on systematically charting the phase space of 2D lead bromide perovskites, it is timely and critical to review the structure-property relationships that are emerging in this family of materials. In this review, we assess the multitude of (100)-orientated lead bromide perovskites, as well as the idiosyncratic (110)-orientated members. We examine the underpopulated phase space of bulk, thick-layer (n > 1) lead bromide perovskites, highlighting several examples of structures violating Goldschmidt's tolerance factor with large organic spacers in the cuboctahedral perovskite cages. The narrow and broadband emission is discussed, along with the developed optoelectronic profile of bulk, lead bromide perovskites, as yet. Lastly, we summarize the integration of 2D lead bromide perovskites in optoelectronic devices.

“…These characterizations endow the bulk low‐dimensional perovskites with ultrahigh luminescent efficiency, which is independent of material morphologies and particle sizes. Especially, the 2D layered perovskites possess natural quantum well characterizations, in which the well and barrier width mainly dependent on the thickness of inorganic layer [39–41] . Therefore, it is convenient to fine‐tune the confinement and exciton binding energy through rationally controlling the thickness of inorganic layer.…”

Mn2+ doped colloidal three‐dimensional (3D) lead halide perovskite nanocrystal (PNC) has attracted intensive research attention; however, the low exciton binding energy and fatal optical instability of 3D PNC seriously hinder the optoelectronic application. Therefore, it remains significant to explore new stable host perovskite with strongly bound exciton to realize more desirable luminescent property. In this work, we utilized bulk one‐dimensional (1D) hybrid perovskite of [AEP]PbBr5 ⋅ H2O (AEP=N‐aminoethylpiperazine) as structural platform to rationally optimize the luminescent property by a controllable Mn2+ doping strategy. Significantly, the series of Mn2+‐doped 1D [AEP]PbBr5 ⋅ H2O show enhanced energy transfer efficiency from the strongly bound excitons of host material to 3d electrons of Mn2+ ions, resulting in tunable broadband light emissions from weak yellow to strong red spectral range with highest photoluminescence quantum yield up to 28.41 %. More importantly, these Mn2+‐doped 1D perovskites display ultrahigh structural and optical stabilities in humid atmosphere, water and high temperature exceeding the conventional 3D PNC. Combined highly efficient, tunable and stable broadband light emissions enable Mn2+‐doped 1D perovskite as excellent down‐converting phosphor showcasing the potential application in white light emitting diode. This work not only provides a profound understanding of low‐dimensional perovskites but also opens a new way to rationally design high‐performance broadband light emitting perovskites for solid‐state lighting and displaying devices.
