Undoped, manganese (Mn) and and chromium (Cr)-doped ZGO were synthesized through microwave-assisted hydrothermal methods. The as-synthesized and thermal annealed materials were morphological and structurally characterized, and the optical properties of these willemite prismatic nanorods were thoroughly investigated. A room temperature (RT) bandgap energy close to 236 nm (∼5.25 eV) was obtained, which is slightly higher than the values reported so far in the literature. Furthermore, optically active absorption and luminescence bands from the ultraviolet to near-infrared were identified. All samples present intrinsic defect absorption with a maximum at 271 nm (∼4.58 eV) and a charge transfer Mn²⁺-O^2- absorption band at 315 nm (∼3.94 eV). In addition, the so-called bluish-white structureless broad emission band is observed at RT at ca. 480 nm (∼2.58 eV) for all the analyzed samples. Our investigation indicates that this band is due to the overlap of two emitting centers: an intrinsic defect originating a blue luminescence (BL) and the ⁴T₁→⁶A₁ intraionic transition of Mn²⁺ leading to a green luminescence (GL), confirming Mn as a common contaminant in this matrix. For the Cr-doped samples, the thermal annealing treatment was seen to promote changes in the visible and near infrared (NIR) intraionic absorption bands. This enabled the identification of the presence of trivalent and tetravalent Cr ion charge states. Additionally, temperature-dependent photoluminescence measurements were carried out in the case of the as-synthesized ZGO:Mn, which is the sample with the highest GL intensity. It was found that the intensity of GL decreases with temperature (from 18 K to RT), with a thermal activation energy of 18 ± 2 meV for the nonradiative processes that compete with the observed luminescence. Moreover, persistent emission from the Mn²⁺ GL was recorded for at least 5 s and was attributed to multi-trapping/de-trapping processes occurring at different trap depths, which are responsible for the distinct decays observed.</div></div>","PeriodicalId":18227,"journal":{"name":"Materials Chemistry and Physics","volume":"334 ","pages":"Article 130463"},"PeriodicalIF":4.3,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrodes were then treated using a furnace and nitrogen atmospheric pressure plasma jet (APPJ) to convert LiCl–Mn(NO₃)₂·4H₂O into LiMn₂O₄. Subsequently, the rGO electrode, LiMn₂O₄ electrode, and PVA-Li₂SO₄ gel electrolyte were combined to form rGO/LiMn₂O₄ flexible ASC. The results of electrochemical measurement showed that the ASCs treated with a combination of furnace and APPJ exhibited better performance compared to those treated with APPJ alone. At a charging/discharging current of 4 mA, the areal capacitance of ASC treated with APPJ is 5 times higher than that of the untreated sample. Furthermore, the areal capacitance after combined furnace and APPJ treatments is improved by 7.5 times compared to the untreated sample. This improvement is likely due to the more uniform and prolonged heating provided by the furnace, allowing the pastes to more completely be converted into LiMn₂O₄ and coat the carbon cloth fibers more evenly. Bending tests and stability tests were also conducted. The results showed that the ASCs treated with both the furnace and APPJ exhibited excellent performance under different curvatures.

Thus, this study involved the synthesis of MBGMs based on 45S5 and 58S glasses, using a nitrate-free sol-gel/microemulsion method. The preferred precursors were selected based on the sol stability, X-ray Diffractometry (XRD), and Simultaneous Thermal Analysis (STA) of the resultant powders.
