Recently, organic-inorganic hybrid metal halides (OIHMs) have been effective white light emitters. Still, the toxicity and instability of lead halides limit their applications. Sb has a relatively similar structure to Pb making it a better substitution. In this work, we synthesized zero-dimensional antimony-based OIMHs (BTBAC)2SbCl5 and (BTBAB)2SbBr5 [BTBA+ (BTBA+ = benzyl tributyl ammonium ion)]. The chloride photoluminescence quantum yield (PLQY) is 72.69% and that of bromide is 17.33%. Spectral tunability from red to yellow is observed after halogen substitution. Density-functional theory (DFT) calculations show that halogens change the bandgap structure from (BTBAC)2SbCl5 direct bandgap to (BTBAB)2SbBr5 indirect bandgap. In addition, (BTBAC)2SbCl5 has excellent thermal stability at 455.15 K and optical properties with strong electron-phonon coupling producing broadband self-trapped exciton (STE) emission. By mixing (BTBAC)2SbCl5 with a commercial phosphor, a white LED with a color rendering index of 87 was created. We have demonstrated the photoluminescence properties of OIMH materials in terms of the series of halogen atoms. This work injects new innovative ideas for the design of novel photoluminescent materials.

Comprehensive Summary Extreme ultraviolet (EUV) lithography is a key technology for sub-7 nm nodes semiconductor manufacturing but faces challenges due to low energy conversion efficiency and weak sensitivity of photoresists. Antimony (Sb)-based materials have attracted increasing attention for their high EUV absorption cross-section. Herein, through a fluorine modification strategy, we functionalized a Sb 2 -oxo cluster with tailored carboxylic acid ligands to achieve dual-tone photoresist control. Crucially, fluorinated ligands induced positive- tone patterning with enhanced sensitivity, while the non-fluorinated ligand decorated Sb 2 -oxo cluster maintained conventional negative-tone behavior. Combined X-ray photoelectron spectroscopy (XPS) analysis, UV-vis absorption spectroscopy analysis, and theoretical calculations highlight the potential of fluorine to alter the inherent cross-linking mechanisms. This work not only enriches the examples of metal oxo cluster based positive photoresists but also provides an effective approach to manipulating photoresist polarity at the molecular level.

Antimony-based electrode materials with conventional slurry-casting process still face great challenges such as tedious preparation process and unsatisfying cycling stability for sodium ion batteries (SIBs). Therefore, the design and fabrication of integrated electrodes with binder-free and even current collector-free are highly significant. Herein, we fabricated flexible Sb/Sb 2 O 3 -C nanofibers (NFs) films utilizing a facile combination of electrospinning technique and carbonization . Sb/Sb 2 O 3 nanoparticles are well embedded in carbon NFs with a fiber diameter of ca. 340 nm. The fabricated NFs films can be directly used as binder and current collector-free anodes for SIBs and exhibited high-capacity and long-lifetime cycles (385.6 mAh g −1 over 500 cycles). Ex situ SEM and TEM observations re-appear their intact fibrous network morphology and stable one-dimensional composite structures after hundreds of discharging-charging cycles, demonstrating that Sb/Sb 2 O 3 -C NFs film is a promising binder-free electrode for SIBs.

Antimony-based materials with high capacities and moderate potentials are promising anodes for lithium-/sodium-ion batteries. However, their tremendous volume expansion and inferior conductivity lead to poor structural stability and sluggish reaction kinetics. Herein, a double-confined nanoheterostructure Sb/Sb 2 S 3 @Ti 3 C 2 T x @C has been fabricated through a solvothermal method followed by low-temperature heat treatment. The dual protection of “MXene” and “carbon” can better accommodate the volume expansion of Sb/Sb 2 S 3 . The strong covalent bond (Ti–S, Ti–O–Sb, C–O–Sb) can firmly integrate Sb-based material with Ti 3 C 2 T x and carbon, which significantly improves the structure stability. In addition, the carbon layer can restrain the oxidation of MXenes, and the nano-Sb/Sb 2 S 3 can facilitate electron/ion transport and suppress the restacking of MXenes. The heterogeneous interface between Sb and Sb 2 S 3 can further promote interfacial charge transfer. The MXene-Sb/Sb 2 S 3 @C-1 with the optimal Sb content shows high specific capacities, comparable rate properties and ultra-stable cycling performances (250 mAh·g −1 after 2500 cycles at 1 A·g −1 for sodium-ion batteries). Ex situ X-ray diffractometer (XRD) test reveals the storage mechanism including the conversion and alloying process of MXene-Sb/Sb 2 S 3 @C-1. Cyclic voltammetry (CV) test results demonstrate that the pseudocapacitance behavior is dominant in MXene-Sb/Sb 2 S 3 @C-1, especially at large current. This design paves the way for exploring high-performance alloy-based/conversion-type anode for energy storage devices. Graphical abstract
