In recent years, low-dimensional organic–inorganic hybrid metal halides (OIHMHs) have shown excellent photophysical properties due to their quantum structure, adjustable energy levels, and energy transfer between inorganic and organic components, which have attracted extensive attention from researchers. Herein, we synthesize a zero-dimensional (0D) OIHMH, Sb3+:(Gua)3InCl6, by introducing Sb3+ into (Gua)3InCl6, which undergoes a significant enhancement of the emission peak at 580 nm with the photoluminescence quantum yield (PLQY) boosted from 17.86 to 95.72% when excited at 340 nm. This boost in photoluminescence of the doped sample was studied by combining ultrafast femtosecond transient absorption, temperature-dependent photoluminescence (PL) spectra, and density functional theory (DFT) calculation, revealing the process of self-trapped exciton (STE) recombination to emit light at both Sb and In sites in this 0D structure simultaneously. This material with the lowest dark STE level at the In site for emission in the undoped sample can amazingly yield very strong emission in the doped sample, which has never been observed before. Finally, we tested its application in a photoelectric device. This work not only helps to gain a deeper understanding of the formation of STEs in In-based halides but also plays a certain guiding role in the design of new luminescent materials.

Lead-free double perovskites (LFDPs) usually exhibit poor luminescent performance, and doping lanthanide ions (Ln 3+ ) presents a promising solution to solve this problem. However, most Ln 3+ ions face difficulties in incorporating into LFDPs due to the mismatch in radius or valence state. Here, we successfully synthesized rare-earth (RE 3+ ) based Cs 2 NaLuCl 6 (CNLC) LFDPs and achieved efficient green emission through doping Tb 3+ into CNLC. Introducing Sb 3+ improves the absorption efficiency of CNLC: Tb 3+ from 25.1 % to 73.5 % by establishing an energy transfer channel from Sb 3+ to Tb 3+ . Benefiting from the energy transfer, the CNLC: 0.01Sb 3+ , 0.10Tb 3+ phosphor produces blue-green dual emissions, highlighting its potential in white light-emitting diodes (WLEDs). In addition, an anti-counterfeiting pattern composed of CNLC: Sb 3+ , CNLC: Tb 3+ , and CNLC: Sb 3+ , Tb 3+ samples was fabricated, which shows their promising prospect in anti-counterfeiting applications.

Sb3+, with a 5s2 electron configuration, has been widely studied as a dopant for its efficient self-trapped exciton (STE) broadband emission. However, the efficient emission of Sb3+-doped one-dimensional (1D) structures and the energy/charge transfer between the host and dopant are rarely reported. In this paper, a series of Sb3+-doped 1D (TDMP)CdCl4 (TDMP = trans-2,5-dimethylpiperazine) powder crystals were prepared by the solvothermal method. The 1D quantum confinement effect and Jahn–Teller distortion in this organic–inorganic hybrid with a soft lattice generate strong electron–phonon coupling. In addition, we also found a fast energy transfer process between the host ([CdCl6]2–) and the dopant ([SbCl6]3–). The synergy of strong electron–phonon coupling and fast energy transfer enables 8.8% Sb3+:(TDMP)CdCl4 to exhibit efficient broadband yellow emission under UV excitation with a photoluminescence quantum yield (PLQY) of 99.69%. DFT calculations indicate that the emission comes from the triplet self-trapped excitons (STEs) emission of the [SbCl6]3– octahedron. This work provides a deeper understanding of the emission of Sb3+ in doped systems and provides a strategy to guide the design of future efficient luminescent materials.

Organic–inorganic metal hybrid halides (OIMHs) as a new kind of photoelectric material have gained much attention in recent years because of their excellent performance in solid-state lighting applications. However, the preparation of most OIMHs is complex and requires a long preparation time in addition to the solvent providing the reaction environment. This greatly limits their further applications. Here, we synthesized zero-dimensional lead-free OIMH (Bmim)2InCl5(H2O) (Bmim = 1-butyl-3-methylimidazolium) by a facile grinding method at room temperature. Through Sb3+ doping, Sb3+:(Bmim)2InCl5(H2O) shows a bright broadband emission centered at 618 nm under UV excitation, which could be attributed to the self-trapped exciton (STE) emission of Sb3+ ions. To explore their ability in the field of solid-state lighting, a white-light-emitting diode (WLED) device based on Sb3+:(Bmim)2InCl5(H2O) with a high color rendering index of 90 was fabricated. This work enriches In3+-based OIMHs and provides a new direction for the simple fabrication of OIMHs.

Sb3+ with stereochemically active lone pair 5s2 electrons is overwhelming in the doping engineering of the luminescent metal halides, and it usually leads to extrinsic self-trapped excitons (STEs) with tunable emissions. However, the photoluminescence enhancement mechanism of Sb3+ doped metal halides compared to the pristine host remains unclear. Herein, we doped Sb3+ into all-inorganic non-emissive Rb4CdCl6, realizing bright green emission peaking at 525 nm with a photoluminescence quantum yield of 70.2%. A comparison of Raman spectra, as well as the Debye temperature, was utilized to elucidate the STEs mechanism, verifying that the doping of Sb3+ softens the structural lattice. Thus, strong electron–phonon interactions enable highly efficient photoluminescence originating from STEs emission in Rb4CdCl6:Sb3+. This work demonstrates solid evidence that the efficient emissions of metal halides can be triggered by Sb3+ doping, and the design principle involved will guide the future studies for emerging luminescence material exploration.

All-inorganic bismuth-halide perovskites are promising alternatives for lead halide perovskites due to their admirable chemical stability and optoelectronic properties; however, these materials deliver inferior photoluminescence (PL) properties, severely hindering their prospects in lighting applications. Here, a novel air-stable but non-emissive perovskite Rb 3 BiCl 6 is synthesized, and the material is used as a prototype to uncover origin of the poor optical performance in bismuth-halide perovskite. It is found that the extremely strong exciton–phonon interactions with a large coupling constant up to 693 meV leads to the seriously nonradiative recombination, which, however, can be effectively suppressed to 347 meV by introducing Sb 3+ ions. As a result, Sb 3+ -doped Rb 3 BiCl 6 exhibits a stable yellow emission with unprecedented PL quantum yield up to 33.6% from self-trapped excitons. Systematic spectroscopic characterizations and theoretical calculations are carried out to unveil the intriguing photophysical mechanisms. This work reveals the effect of exciton–phonon interaction, that is often underemphasized, on a material's photophysical properties.

Organic-inorganic metal halides (OIMH) doped with Sb 3+ often exhibit excellent optoelectronic properties, however, their photoluminescence (PL) mechanisms, especially after Sb 3+ doping, require a deeper understanding of their excited states and optical transitions. Through synergistic analysis of temperature-dependent PL and femtosecond transient absorption (fs-TA） spectroscopic study, the coexistence of dual polaronic states and their temperature-dependent transient bipolaronic state absorption processes in 0D Sb 3+ :(C 2 H 8 N) 4 InCl 7 system have been identified: (1) Sb 3+ -site polaron or self-trapped exciton(STE) emission originating from spin-allowed ( 3 P 1 → 1 S 0 ) and ( 1 P 1 → 1 S 0 ) in SbCl 6 octahedra) is favorably formed first, giving emission at 615 nm at room temperature; (2) In 3+ -Sb 3+ donor-acceptor pair (DAP) STE (In 3 P 1 → Sb 1 S 0 ) can be produced under 111.2 cm −1 Longitudinal Optical (LO) phonon assistance at 160 K and giving emission 700 nm at room temperature. Both polaronic states can collaborate to give the broad emission with a photoluminescence quantum yield (PLQY) of 98.4%. Though 0D structure, close energy span between Sb(III) and In(III) can cause such DAP behavior for Sb 3 ⁺ with 5s 2 electrons in the In-Cl matrix, this provides key insights into the radiation synergy effects with the host via short and long-range phonons. This model paves the way for developing novel high-performance luminescent materials for optoelectronic applications.

The development of efficient and environmentally benign luminescent materials is of paramount importance for sustainable lighting and display technologies. This study presents a novel zero-dimensional (0D) organic-inorganic hybrid metal halides (OIHMHs), (Cyt) 2 InCl 5 ·H 2 O:Sb 3+ , with tunable white-light emission through synergistic organic-inorganic interactions and Sb 3+ doping. The incorporation of Sb 3+ ions through doping establishes energy transfer pathways from singlet exciton recombination (S 1 ) and triplet exciton recombination (T 1 ) energy levels to self-trapped excitons (STEs), thereby enabling precise control over fluorescence emission and phosphorescence characteristics. This strategic modification concurrently enhances the photoluminescence quantum yields (PLQYs) and thermal stability the material. Density functional theory (DFT) calculations further provide insights into the electronic structure and defect-related properties of the crystals. The Sb 3+ -doped (Cyt) 2 InCl 5 ·H 2 O materials demonstrate excellent performance in solid state lightings, achieving high color rendering index (CRI) and adjustable correlated color temperature (CCT). Additionally, the long-persistent luminescence and X-ray scintillation properties are explored for anti-counterfeiting and radiation detection applications.

Organic–inorganic hybrid metal halides have attracted considerable attention due to their facile synthesis, low cost, and high thermal and chemical stability. However, developing environmentally benign, readily synthesized, high-performance, and spectrally tunable broadband-emitting materials remains challenging. Herein, this study reports a zero-dimensional perovskite material, TEA2HfCl6:Sb3+, using a room-temperature coprecipitation method. This material exhibits low toxicity and excitation-wavelength-dependent modulation of singlet and triplet emission ratios, enabling broadband emission ranging from warm white to deep red. Notably, TEA2HfCl6:11%Sb3+ achieves a high photoluminescence quantum yield of up to 93.1%. Steady-state and time-resolved spectroscopic analyses reveal that these emissions arise from Sb3+-induced radiative transitions of singlet and triplet self-trapped excitons. Furthermore, leveraging its scalable synthesis process and favorable emission characteristics, the material shows potential for applications in large-area optical anticounterfeiting paper and full-spectrum, eye-friendly white-light-emitting diode (WLED). These findings highlight the dual functionality of TEA2HfCl6:Sb3+ in secure optical encryption and solid-state lighting, providing a promising platform for the development of multifunctional luminescent materials.

Recently, Sb3+-doped all-inorganic vacancy-ordered double perovskites A2SnCl6 (A = K, Rb, and Cs) have attracted wide attention because of their unique optoelectronic properties and excellent stability. However, Sb3+-doped A2SnCl6 generally exhibits poor emission intensity. To overcome this, we take the all-inorganic A2SnCl6 as the conformational model and utilize a universal supramolecular assembly strategy to develop three different organic metal halides with dumbbell structures of (KC)2SnCl6:Sb3+, (RbC)2SnCl6:Sb3+, and (CsC)2SnCl6:Sb3+ (C = 18-crown-6). Compared with Sb3+-doped A2SnCl6 shows poor emission intensity, Sb3+-doped (AC)2SnCl6 exhibits the efficient tunable white emission with photoluminescence quantum yield (PLQY) of 86.7% for (KC)2SnCl6:Sb3+, 81.6% for (RbC)2SnCl6:Sb3+, and 89.8% for (CsC)2SnCl6:Sb3+, which stems from Sb3+-induce Jahn-Teller-like singlet and triplet self-trapped excitons (STEs) emission. Particularly, there eruptive PLQY obtained in Sb3+-doped (AC)2SnCl6 can be attributed to the strong supramolecular interactions increasing the structural rigidity and thus inhibiting non-radiative transitions. Longer Sb-Sb distances in Sb3+-doped (AC)2SnCl6 facilitate the expression of Sb3+ 5s2 lone pairs. Moreover, Sb3+-doped (AC)2SnCl6 also has an excellent chemical- and photo-stabilities. Finally, taking Sb3+-doped (KC)2SnCl6 as an example, we further demonstrated its applications in single-compound white light-emitting diodes (WLED) at room temperature, multiple-mode optical anti-counterfeiting, and information encryption.
