A comparative analysis of different types and concentrations of surfactants was conducted to determine the optimal conditions for synthesis. The resulting Bi₂MoO₆ features a mesoporous architecture composed of interconnected nanosheets with an average pore size of approximately 3 nm. Characterization results reveal that this dual approach of surfactant addition and pH control effectively modulates the morphology and optimizes the band gap energy levels of bismuth molybdate materials, significantly enhancing the specific surface area. Notably, Bi₂MoO₆ synthesized with 0.2 mmol of L-Tartaric acid (TA) achieved an exceptionally high response value of 118 to 100 ppm ethanol at an operating temperature of 200 °C, and the sensor demonstrated a practical detection limit as low as 20 ppb (S = 4.13), showcasing its high sensitivity. Additionally, the sensors demonstrated remarkable selectivity for ethanol, outperforming other gases in the concentration range of 100 ppm to 20 ppb. These findings underscore the promise of Bi₂MoO₆ gas sensors prepared via surfactant addition and pH control for the rapid and sensitive detection of low ethanol concentrations at low temperatures. This method could have significant implications for environmental monitoring and industrial safety applications, where the detection of trace levels of ethanol is critical. This Bi₂MoO₆-based sensor, with its combination of high sensitivity, selectivity, and stability, stands out as a valuable tool for advanced gas sensing applications.</p></div>","PeriodicalId":646,"journal":{"name":"Journal of Materials Science: Materials in Electronics","volume":"36 14","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the influence of La doping on the phase evolution, microstructure, critical transition temperature, and flux pinning properties of Bi-2212 was investigated. The results indicate that La doping significantly promotes the formation of the Bi-2212 phase. As the La content increases, the a and b axis lengths of Bi-2212 structure gradually increase, while the c-axis length decreases. The La doping will introduce compressive stress into the Bi-O layers. Meanwhile, the modulation structure in Bi-2212 becomes enhanced with La substitution by decreasing the modulation period, which is effectively explained by the extra oxygen model. Furthermore, the critical transition temperatures (<span>(T_c^{onset})</span>) initially increases and then decreases with higher La doping levels, reaching a maximum <span>(T_c^{onset})</span> of 85.9 K for the sample with x = 0.15.

According to the optical analysis, the band gap is 4.69 eV, and the optical absorbance occurs at 264-nm. The Thermogravimetric analysis (TGA) was used to evaluate the thermal stability and breakdown profile of 5MLG. The results indicate that the material is thermally stable up to 189 °C.

The microhardness tests proved that the crystal was mechanically stable up to 100 g, showing that it had strong physical properties suitable for device fabrication. The presence of all four forms of polarization is demonstrated by the strong dielectric constant at low frequencies, which is crucial for nonlinear applications. Second harmonic generation (SHG), which is 1.1 times more efficient than KDP, proved that the material could be used to double the frequency.
