摘要
这项研究探讨了采用熔淬技术合成的改性硼钒玻璃体系中不同成分玻璃样品的交流电导率、阻抗光谱和模量配方。随着氧化硼含量的增加,交流电导率呈上升趋势,最高可达 10 摩尔%;然而,当 x = 15&20 摩尔% 时,交流电导率有所下降。Almond West 模型拟合了交流电导率的实验数据,并得出了交叉频率、频率指数 (s) 和直流电导率 \((\sigma_{\text{dc}})\)等参数。除了具有小极子量子力学机制的 VBa1 外,所有样品在不同频率下都具有 CBH 传导机制。从电导率(0.565-0.742 eV)、电模量(0.526-0.616 eV)和阻抗研究(0.530-0.743 eV)得出的活化能具有良好的一致性。介电研究显示了非德拜型行为。根据阻抗形式主义,电传导是通过 Ba2+ 离子和电子/极子实现的。这一特性使这种玻璃非常适合用于储能设备。
Uncovering the impact of BaO on electrical properties of bismuth boro vanadate glasses: V2O5-B2O3-Bi2O3-BaO
This work investigates the AC conductivity, impedance spectroscopy, and modulus formulation of varied compositions of glass samples within the modified borovanadate glassy system, synthesized using the melt-quenching technique. Up to 10 mol% of BaO, the AC conductivity shows a rising trend as BaO content rises; however, for x = 15&20 mol%, there is a drop. The Almond West model fits the experimental data of ac conductivity and parameters such as crossover frequency, frequency exponent (s), and direct current conductivity \((\sigma_{\text{dc}})\) are retrieved. All samples feature a CBH conduction mechanism at varying frequencies, except for VBa1, which has a small polaron quantum mechanical mechanism. There is good agreement in the activation energy derived from conductivity (0.565–0.742 eV), electric modulus (0.526–0.616 eV), and impedance research (0.530–0.743 eV). Dielectric studies reveal non-Debye-type behavior. According to impedance formalism, electric conduction occurs through Ba2+ ions and electron/polarons. This characteristic renders the glasses well-suited for energy storage devices.
