Manganese doped lithium strontium borate glasses with chemical composition 25Li₂O-15SrO-(60-x)B₂O₃-xMnO are prepared through the classical melt-quenching method and characterized by various techniques like XRD, DSC, optical absorption, EPR, Impedance spectra and AC conductivity. The XRD and DSC studies revealed the amorphous glassy nature of the prepared samples. The optical absorption spectra of the prepared inorganic glassy samples depict a single extensive absorption band at 470 nm attributed to the ⁶A_1g(S)→⁴T_1g(G) transition of Mn²⁺ ions belonging to d⁵ configuration in the octahedral symmetry sites. These spectra also substantiated that the octahedral Mn²⁺ ions were prevailing up to 0.8 mol% of MnO. The optical band gap energy and Urbach energies were evaluated from these spectra. The EPR spectra show three resonance signals positioned at g ≈ 2.0, 3.1 and 4.3 due to the Mn²⁺ paramagnetic ions. The resonance peak perceived at g ≈ 2.0 gives a predominant six-line hyperfine structure (hfs), a principal signature of Mn²⁺ ions. The hyperfine constant (A_avg), spin concentration (N), paramagnetic susceptibility ($\mathrm{\chi }$) and zero-field splitting (D) parameters of the prepared glass samples were evaluated and analyzed. The Nyquist (Cole-Cole) plots exhibit only one well-shaped semicircle (single-phase) throughout all the temperatures, which confirms the good homogeneity of the current glass system. The AC conductivity values of the prepared glassy samples are amplified with temperature and frequency. The AC conductivity values changed from 10⁻⁸ to 10⁻³ Ω⁻¹cm⁻¹. The LSBM8 glass sample has the highest AC conductivity; hence these glassy inorganic materials are suitable for solid-state battery applications and other opto-electronic device applications.

_{采用经典的熔融淬火法制备了化学成分为25Li 2} O-15SrO-(60-x)B ₂ O ₃ -xMnO的锰掺杂硼酸锶锂玻璃，并通过XRD、DSC、光吸收、EPR、阻抗谱和交流电导率。XRD 和 DSC 研究揭示了制备的样品的无定形玻璃性质。制备的无机玻璃样品的光学吸收光谱描绘了在 470 nm 处的单个宽吸收带，归因于属于 d ^{5的 Mn 2+离子的6} A _1g (S)→ ⁴ T _1g (G) 跃迁八面体对称位点的构型。这些光谱还证实八面体Mn ²⁺离子占MnO的0.8 mol%。从这些光谱中评估了光学带隙能量和 Urbach 能量。由于 Mn ²⁺顺磁性离子，EPR 光谱显示了位于 g ≈ 2.0、3.1 和 4.3 的三个共振信号。在 g ≈ 2.0 处感知到的共振峰给出了主要的六线超精细结构 (hfs)，这是 Mn ²⁺离子的主要特征。超精细常数 (A _avg )、自旋浓度 (N)、顺磁化率 ($\mathrm{\chi }$) 和制备的玻璃样品的零场分裂 (D) 参数进行了评估和分析。Nyquist (Cole-Cole) 图在所有温度下仅显示出一个形状良好的半圆（单相），这证实了当前玻璃系统的良好均匀性。制备的玻璃状样品的交流电导率值随温度和频率而放大。AC电导率值从10 ^-8变为10 ^-3  Ω ^-1 cm ^-1。LSBM8玻璃样品具有最高的交流电导率；因此，这些玻璃状无机材料适用于固态电池应用和其他光电器件应用。
