The results of the calculations indicate that the lattice constants change sharply at around 0.9 GPa and the c-axis is more compressible than the a- and b-axes. We observe the most striking changes in interatomic Tl–Ga distances. Our investigation results show that TlGaSe₂ undergoes a pressure-induced isostructural phase transition. We have calculated how elastic constants and different elastic properties, like bulk modulus, shear modulus, Young’s modulus, Poisson’s ratio, and Raman active modes, change with pressure. By clarifying the pressure-dependent behavior of TlGaSe₂, this work contributes to the broader understanding of layered semiconductors under compression. Beyond clarifying the pressure-induced phase transition mechanism, our results provide theoretical support for the use of TlGaSe₂ under high pressure in radiation detection, photoacoustic devices, and broadband photodetectors, as suggested in earlier experimental studies.</p><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":664,"journal":{"name":"Journal of Sol-Gel Science and Technology","volume":"118 1","pages":""},"PeriodicalIF":3.2,"publicationDate":"2026-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10971-026-07153-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147737384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Structural analysis confirmed the formation of cubic spinels with nanometric crystallite sizes (23–28 nm) and high thermal stability. Surface area and porosity, evaluated by BET analysis, increased with Mg content, reaching 33.0 m²/g at x = 0.8, while X-ray photoelectron spectroscopy revealed systematic changes in surface redox states and oxygen species, notably the decline of Cu²⁺ and the evolution of defect-related oxygen. Optical studies showed band gap widening from 1.94 to 2.42 eV with increasing Mg substitution, reflecting changes in Cu–O and Fe–O hybridization that modulate visible-light absorption and charge carrier dynamics. Photocatalytic tests under visible light and in the presence of H₂O₂ demonstrated composition-dependent degradation efficiencies toward methylene blue (MB), rhodamine B (RhB), and malachite green (MG). Cu-rich compositions (x = 0.2–0.4) achieved the highest photocatalytic activity for MB and RhB, while Mg-rich ferrites exhibited superior performance for MG, including efficient degradation under dark conditions via a heterogeneous Fenton-like mechanism.

Surface morphology analysis via scanning electron microscopy (SEM) revealed distinct structural variations, with PVP-assisted Bi₂WO₆ displaying a uniform flower-like architecture. The optimised hydrothermal conditions, particularly the use of polyvinylpyrrolidone (PVP) and cetyltrimethylammonium bromide (CTAB), played a crucial role in achieving the flower-like Bi₂WO₆ morphology.
