Single-crystal X-ray diffraction revealed its triclinic symmetry and distinct inorganic chain alignment. Optical investigations demonstrated a direct band gap of 3.59 eV and strong blue-violet photoluminescence with excitation-dependent chromaticity, a feature rarely reported in similar bismuth-based systems.

In this work, we employed first-principles density functional theory (DFT) computations to examine the structural, electrical, optical, mechanical, and thermal properties of non-toxic Na<sub>3</sub>OX (X = Cl, I) anti-perovskites under a range of hydrostatic pressures from 0 to 500 GPa. The stability of these compounds is confirmed by our structural results, which agree with earlier theoretical investigations. Both Na<sub>3</sub>OCl and Na<sub>3</sub>OI have relatively broad bandgaps, which are much diminished when hydrostatic pressure rises. This makes them suitable for usage in solar energy and semiconductor applications. These materials are promising candidates for optoelectronic devices such as UV detectors, waveguides, solar cell anti-reflection coatings, organic light-emitting diodes (OLEDs), and quantum dot light-emitting diodes (QLEDs) because the application of pressure results in improved optical behavior, such as increased static dielectric constants, extended absorption in the ultraviolet range, and decreased visible reflectance. Anisotropic nature, strong thermal stability, and a change from brittle to ductile behavior at high pressure are all revealed by mechanical analysis. Their suitability for use in robust device environments is further supported by the improvement in ductility and elastic characteristics under compression. All things considered, the tunability and multifunctional potential of Na<sub>3</sub>OCl and Na<sub>3</sub>OI anti-perovskites are demonstrated in this thorough investigation, providing important information for further study and advancement in pressure-engineered optoelectronic and energy materials.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"348 ","pages":"Article 131612"},"PeriodicalIF":4.7,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145155563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
