“…The investigation of the affection on luminescent properties of two different methods is in process. However, the position and the relative intensity of the excitation band of the title compound is similar with that reported Sb 3+ -doped Ca 5 ðPO 4 Þ 3 OH obtained from the hydrothermal system earlier [21].…”

“…In 1999, doped colloidal nanomaterials of LaPO 4 :Eu, LaPO 4 :Ce and LaPO 4 :Ce,Tb have been prepared through a hydrothermal method by Haase et al [17]. Sb 3+ -doped and Sb 3+ and Mn 2+ co-doped hydroxyapatite were synthesized from hydrothermal system by Chen et al [21] and investigated the luminescent properties of Sb 3+ and Mn 2+ in the compounds. And the energy transfer from Sb 3+ ion to Mn 2+ ion was observed.…”

“…Therefore, grinding is often needed, which however, produces defects that can act as non-radiative recombination sites to reduce the luminescent efficiency [19]. Hydrothermal technique, one of the direct synthesis methods for phosphor, has been attracted more attention because of the relative mild reaction conditions and the high-crystallized particles with narrow grain size-distribution [20], and has also been successfully employed to prepare luminescent materials [21][22][23][24].…”

“…On the other hand, it has been well known that the emission color can be controlled through changing the Sb 3 + /Mn 2 + ratio in the (Sb 3 + , Mn 2 + ) co-doped Ca 10 (PO 4 ) 6 X 2 (X = F, Cl) commercial phosphor due to the blue emission of Sb 3+ ions and the yellow emission of Mn 2+ ions in the compounds [23]. Because Eu 3+ -doped YBO 3 was a promising orange-red emission luminescent material [2,16] and Sb 3+ -doped YBO 3 was a blue one, we introduced both Sb 3+ and Eu 3+ ions into YBO 3 through a hydrothermal process to obtain nearly white light luminescent materials.…”

“…Trivalent Sb 3+ ion as a well-known activator has been widely investigated in many host materials such as Ca 10 (PO 4 ) 6 X 2 (X = F, Cl) [25], Ca 10 (PO 4 ) 6 (OH, X), Ca 10 (PO 4 ) 6 (OH) 2 [23], Sr 3 (PO 4 ) 2 [26], LnPO 4 (Ln = Sc, Lu, Y) [27], Cs 2 NaMCl 6 (M = Sc, Y, La) [28] and YBO 3 [29]. The research results show that Sb 3+ ion is a good activator for blue light when it is coordinated in a suitable surrounding.…”

Sb 3+ -doped YBO 3 crystals were prepared through a low-temperature hydrothermal method and a high-temperature solid-state technique, respectively. The effects of preparation methods on the morphologies and luminescent properties of YBO 3 phosphors were investigated. The YBO 3 crystals from the hydrothermal system look like flowers, whereas those from the solid-state process look like some agglomerates of little spheres. The Sb 3+ -doped YBO 3 powders prepared via both methods showed the blue emission with the peak at around 452 nm, which corresponds to the 3 P 1 ! 1 S 0 transition of Sb 3+ ions. However, the emission intensity of the Sb 3+ -doped YBO 3 from the hydrothermal system is about 3.5 times as much as that from the solid-state process. The (Sb 3+ ,Eu 3+ ) codoped YBO 3 crystals were also prepared through the two methods. The results showed that the emission intensity of Sb 3+ ions in (Sb 3+ , Eu 3+ ) co-doped YBO 3 synthesized by the hydrothermal method is stronger than that by the solidstate process.

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...
