these alternatives with varied crystal structures improved the water/thermal stability and optimized the optical performance of metal halide materials group. [7] ns 2 metal ion-based metal halides have always been regarded as the mainstream materials owing to their excellent optical properties and the facile synthesis procedure. [8] Moreover, ns 2 metal ion-based halides with broad-band emission and large Stokes shift, which can avoid selfabsorption effectively, are desirable for phonic applications. And, the self-trapped excitons (STEs) herein are ascribed to the strong electronphonon coupling in the distorted excited structure. [9] To generate diverse STEs emission in the visible light region, different ns 2 metal ions like Ge 2+ , Sn 2+ , Te 4+ , Bi 3+ , and Sb 3+ are selected to adjust emission peaks due to their different coordination environment and special crystal/local structures. [10] Among ns 2 metal halides, Sb 3+ -based halides with blue, green, and red tunable luminescence have been explored extensively as low-toxic and highly stable candidates, moreover, their luminescence mechanisms are discussed by combined experimental and theoretical methods, as well as their unique singlet and triplet excitonic emission. [5d,e,11] In this review, we first look back the electronic energy levels of ground state and excited state for ns 2 ions and the luminescence of Sb 3+ in transition metal oxides. Next, we summarize the recent progresses of the crystal structures, optical properties, and luminescence mechanisms of some Sb 3+ -based halides and Sb 3+ -doped metal halides including all-inorganic and hybrid organic-inorganic perovskite derivatives. Then, we discuss the current achievements of these materials in the emerging applications. And finally, we offer the perspective and some suggestions on the possible development of luminescent Sb 3+ -based metal halides. Electronic Energy Levels of Sb 3+The luminescence and radiation process of ns 2 ions in solidstate compounds have been widely investigated. [10a,b,d,12] A free Emerging lead-free metal halides with low toxicity and unparalleled optoelectronic properties have attracted growing research interests, also demonstrating extensive application potentials. Among these, Sb 3+ -based allinorganic/organic-inorganic hybrid metal halides become a vital group due to the special energy level distribution along with diverse optical properties. However, there remains a gap in understanding the relationship between the crystal structure and the radiation process of involved Sb 3+ emission. Herein, the existing reports about Sb 3+ -based luminescent metal halides are revisited and their structure-luminescence-application relationship is explored, and it is further established that the triplet self-trapped excitons (STEs) emission of Sb 3+ varies in different crystallographic environments and endows tunable luminescent performance. This work aims to provide constructive strategies in the further exploitation of Sb 3+ -based metal halides, and also guides the structura...

Hybrid 0D Antimony Halides as Air‐Stable Luminophores for High‐Spatial‐Resolution Remote Thermography

et al. 2021

Luminescent organic–inorganic low‐dimensional ns2 metal halides are of rising interest as thermographic phosphors. The intrinsic nature of the excitonic self‐trapping provides for reliable temperature sensing due to the existence of a temperature range, typically 50–100 K wide, in which the luminescence lifetimes (and quantum yields) are steeply temperature‐dependent. This sensitivity range can be adjusted from cryogenic temperatures to above room temperature by structural engineering, thus enabling diverse thermometric and thermographic applications ranging from protein crystallography to diagnostics in microelectronics. Owing to the stable oxidation state of Sb3+, Sb(III)‐based halides are far more attractive than all major non‐heavy‐metal alternatives (Sn‐, Ge‐, Bi‐based halides). In this work, the relationship between the luminescence characteristics and crystal structure and microstructure of TPP2SbBr5 (TPP = tetraphenylphosphonium) is established, and then its potential is showcased as environmentally stable and robust phosphor for remote thermography. The material is easily processable into thin films, which is highly beneficial for high‐spatial‐resolution remote thermography. In particular, a compelling combination of high spatial resolution (1 µm) and high thermometric precision (high specific sensitivities of 0.03–0.04 K−1) is demonstrated by fluorescence‐lifetime imaging of a heated resistive pattern on a flat substrate, covered with a solution‐spun film of TPP2SbBr5.

Luminescent metal halide materials with flexible crystallography/electronic structures and tunable emission have demonstrated broad application prospects in the visible light region. However, designing near‐infrared (NIR) light‐emitting metal halides remains a challenge. Here, an enlightening prototype is proposed to explore the high‐efficiency broadband NIR emission in metal halide systems by incorporating Sb3+ into the Cs2ZnCl4 matrix. Combined experimental analysis and density functional theory calculations reveal a modified self‐trapped excitons model to elaborate the NIR emission. The high photoluminescence quantum yield of 69.9% peaking at 745 nm and large full width at half maximum of 175 nm, along with excellent air/thermal stability, show the unique advantages of lead‐free metal halide Cs2ZnCl4:Sb3+ as the NIR light source. The substitution of Cl− by Br− further enables the red‐shift of emission peak from 745 to 823 nm. The NIR light‐emitting diode device based on Cs2ZnCl4:Sb3+ demonstrates potential as a non‐visible light source in night vision. This study puts forward an effective strategy to design the novel eco‐friendly and high‐efficiency NIR emissive materials and provides guidance for expanding the application scope of luminescent metal halides.
