“…In conclusion, Cs 3 Sb 2 X 9 exhibit broad emission generally due to the involvement of STEs or defect transitions in the lattice. [ 32 ] The narrow emission bands observed in Cs 3 Sb 2 X 9 QDs are due to the quantum confinement effect or different surface state in the synthesis process. Intriguingly, Cs 3 Sb 2 X 9 QDs show high stability and luminescent efficiency, which are conducive to further application.…”

“…Herein, different metal halides were reported to be used as the luminescent layer, therefore, one can realize high CRI in white LEDs and the large Stokes shift can effectively reduce self‐absorption behavior. [ 32a ] However, the optimum excitation wavelength is required to match commercial chips to fabricate highly efficient LEDs devices. In our previous study, yellow‐emitting Cs 2 InCl 5 ·H 2 O:Sb 3+ and commercial blue phosphor was mixed as the white light mixture as shown in Figure a,b.…”

“…Analogously, a red LED based on Cs 3 Sb 2 I 9 were proposed by Chu and co‐workers. [ 32b ] The fwhm of LED is wider than that of PL emission due to redundant parasitic EL signals from interfaces or other possible positions. In the future, the realization of high‐performance LED devices still needs more efforts.…”

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...

The increasing attention on halide perovskite nanocrystals (PNCs) stems from their outstanding optoelectronic properties, especially the intriguing photoluminescence (PL) features. The high photoluminescence quantum yields (up to unity) of PNCs, and the tunability of their optical bandgaps by composition engineering and quantum confinement effects, account for the demonstrated great potential in several optoelectronic applications, such as light‐emitting diodes (LEDs), phosphors, lasers, and photodetectors. However, despite the rapid growth of this research field, several questions are still left unanswered and there is room for further improving the luminescence performance, particularly for emerging lead‐free PNC compositions. Herein, the recent advances in the light emission phenomena in PNCs are discussed. A special focus is given to the correlation between PL and phase transition, the dual‐color emission, the tunability of the PL toward near‐infrared (NIR), and the thermal quenching effect. The key research findings on LEDs, the major application of perovskite‐based nanoscale emitters, are also outlined. Finally, the view on the most urgent challenges to be addressed is provided, with the intent of promoting a more profound understanding of PNC emission‐related phenomena in the future.

Due to their nontoxicity, stability, and unique optoelectronic properties, all‐inorganic lead‐free halide semiconductors with perovskite and perovskite‐like structures have successfully emerged as promising optoelectronic materials for various applications, such as solar cells, light‐emitting diodes (LEDs), photodetectors, and X‐ray detectors. To further explore their practical potentials, researchers have paid more attention in all‐inorganic lead‐free perovskite (‐like) (ILFP) single crystals. For these single crystals, the advantages of large sizes, uniform surface morphology, and few defects can facilitate their excellent performances and practical applications. Besides, compared with the low dimensional and polycrystalline ILFP materials, the ILFP single crystals feature enhanced performances, including a longer carrier diffusion length and a larger light absorption coefficient, which attract a great deal of attention. Therefore, focus is on the researching progress of ILFP single crystals and the development of their preparation methods, as well as the novel properties of ILFP single crystals. In addition, the reported applications of ILFP single crystals are proposed to highlight their practical importance. With the perspective of the evolution and challenges, the current limitations of the materials and devices are discussed, followed by an inspirational outlook on their future development directions.
