X-ray diffraction (XRD) analysis showed that this substitution did not alter the glass’s amorphous structure. However, the density increased slightly, potentially due to the higher molecular mass of Fe₂O₃ compared to Na₂O. This density change suggests a possible alteration in the glass’s optical properties. Optical measurements revealed a shift towards the red spectrum and a decrease in transmittance, particularly at 543 nm, indicating increased optical loss. This loss was attributed to increased reflectance, not absorption. The optical band gaps decreased with higher Fe₂O₃ content, enhancing the glass’s optical resistance, and making it suitable for applications like optical filters and shielding materials. The optical loss tangent analysis showed that the material’s efficiency in transmitting electromagnetic energy decreased with Fe₂O₃ substitution, likely due to changes in the electronic structure. The study also noted that Fe₂O₃ improved optical absorption, as demonstrated by the Hydrogenic Excitonic Model (HEM).</p></div>","PeriodicalId":473,"journal":{"name":"Applied Physics A","volume":"130 11","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we evaluated the photocatalytic performance of the MoS₂/Ag nanocomposite in the degradation of methylene blue and methyl orange dyes under UV and visible light irradiation. The results demonstrated a marked enhancement in photocatalytic efficiency for the MoS₂/Ag nanocomposite, which can be ascribed to the suppression of photogenerated electron-hole pair recombination and the improved electron transport dynamics within the composite structure.

Magnesium diboride (MgB₂) has a critical temperature of 39 K, allowing it to be a suitable replacement for Niobium-based superconductors.

The influence of Gd³⁺ ion substitution on the physical attributes of Sr₂FeTiO₆ (SFTO) was meticulously examined. The basic structure of Sr_2 − xGd_xFeTiO₆ (SGFTO) (x = 0.2 to 0.8), was employed to start the Rietveld structural refinement of the powder X-ray diffraction patterns. This process confirmed the presence of a cubic structure with a space group of <i>Pm3m</i>. The replacement of Gd³⁺ ions, noted for their larger ionic radii, led to a minor increase in the lattice parameters and the volume of the unit cell. The identity of the elements within the compound was determined by examining their oxidation states through X-ray photoelectron spectroscopy. The SEM images reveal that as Gd content increases in the SGFTO samples, the structure becomes denser and more agglomerated, with reduced porosity and less uniform particle sizes. This suggests that higher Gd content leads to a more compact morphology, potentially impacting the material’s electrochemical performance and mechanical stability. The use of diffuse reflectance measurements confirmed that the band gap values decreased slightly from 2.95 eV to 2.24 eV for the Sr_2 − xGd_xFeTiO₆ (x = 0.2–0.8) materials, indicating that these synthesized samples exhibit semiconductor nature. The study investigated how often the dielectric constant and its behavior change with temperature, and these measurements proved that as the amount of Gd³⁺ in the material increased from 0.2 to 0.8, the dielectric constant also increases.
