Glass systems of Bi2O3-ZnO-Li2B4O7-TbF3 [BZLT] were cast by melt-quench process. Transparent glasses were analysed by diffracted Roentgen X-rays. Peak free and broad nature X-ray diffraction revealed the amorphous arrangement prevailing in these glasses. Density was estimated using the Archimedes principle. Bismuth grossly affected the density of BZLT glasses by increasing its value 2.722 gm/cc [BZLT-0] to 4.6739 gm/cc [BZLT-40]. Optical absorption provides valuable information about optical band gap energy and Urbach energy and some of its derived physical quantities. The effect of bismuth is felt in decreased Eopt values [3.312 eV in BZLT-0] [2.619 eV in BZLT-40] in BZLT glasses. Bismuth altered the structure of the borate network by forming non-bridging oxygens which in turn reduced the band gap energy by large margin (ΔEopt = 0.693 eV). Fourier transform infrared spectroscpy and Raman studies revealed the presence of several triangular BO3 and tetrahedral BO4 and BiO3 units and also the existence of metal cation vibrations and supported the large deviations in the optical bandgap energies. Election paramagnetic resonance studies support the presence of Tb3+ ions and absence of Tb4+ions in BZLT glasses.","PeriodicalId":11496,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":"20 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141945788","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}

The SPR sensor improves sensitivity and selectivity for ascorbic acid detection by taking advantage of the special optical characteristics of the multilayer construction. The CNT layer offers increased surface area and biocompatibility, and the Ag layer acts as a plasmonic material to promote surface plasmons. The performance of the sensor is improved by the addition of selenium (Se) and Fe2O3 layers, which provide further capabilities like photoconductivity and magnetic manipulation, respectively. Numerical analysis at the operating wavelength of 633 nm is conducted using the transfer matrix approach. For the proposed SPR sensor at room temperature, the performance characteristics, including sensitivity (274.37 degree (°)/RIU), figure of merit (40.60 RIU−1), and detection accuracy (0.189°−1), are computed.

Here, we describe the effect of alkaline earth metal substitution on the optical, electronic, and photoelectrochemical (PEC) properties of copper metavanadate (CuV2O6). As a host, the Cu-V-O compound family presents a versatile framework to develop such composition-property correlations. Alloy compositions of A0.1Cu0.9V2O6 (A = Mg, Ca) photoanodes were synthesized via a time and energy-efficient solution combustion synthesis (SCS) method. The effect of introducing alkaline earth metals (Mg, Ca) on the crystal structure, microstructure, electronic, and optical properties of copper metavanadates was investigated by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS), transmission electron microscopy (TEM), and Raman spectroscopy. The PXRD, TEM, and Raman spectroscopy data demonstrated the polycrystalline powder samples to be mutually soluble, solid solutions of copper and alkaline earth metal metavanadates and not simple mixtures of these compounds. The DRS data showed a systematic decrease in the optical bandgap with Cu incorporation. These trends were corroborated by electronic band structure calculations. Finally, the PEC properties exhibited a strong dependence on the alloy composition, pointing to possible applicability in solar water splitting, heterogeneous photocatalysis, phosphor lighting/displays, and photovoltaic devices.","PeriodicalId":11496,"journal":{"name":"ECS Journal of Solid State Science and Technology","volume":"18 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141738252","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}

The structural indices (grain size, dislocation density, lattice strain) of the ZTO3 and Li-doped ZTO3 thin films were computed. The morphology characteristics of the ZTO3 and Li-doped ZTO3 thin films were observed by field emission scanning electron microscopy. The inspected films display uniform and homogeneous surfaces. The optical transmittance, T, and reflectance, R, of the ZTO3 and Li-doped ZTO3 thin films were recorded using a double-beam spectrophotometer to investigate the optical characteristics of these layers. The refractive index of the ZTO3 and Li-doped ZTO3 thin films was enhanced via the Li content increase. Moreover, Tauc’s plots demonstrated that the energy gap of the ZTO3 and Li-doped ZTO3 thin films was reduced from 3.85 eV to 3.08 eV by boosting the Li doping content. Moreover, the increase in Li content produces an enhancement in the optoelectrical indices (optical resistivity, optical carrier concentration, optical mobility, plasms frequency, and optical conductivity) of the ZTO3 and Li-doped ZTO3 thin films. The nonlinear optical indices of the ZTO3 and Li-doped ZTO3 thin films were deduced, and it was noted that Li content boosted the nonlinear optical indices of these layers.
