摘要

采用常规熔融淬火法制备了掺Er3+的碲酸锂玻纤玻璃，并通过阻抗分析仪研究了其随温度变化的交流电导率。利用Almond-West型幂律分析了频率相关的交流电导率。电导率随频率和温度的增加而增加。得到的电导率值范围为4.092 × 10−5 ~ 3.024 × 10−5 S/cm。用相关势垒跳变(CBH)模型可以合理地推断交流电导率的机理。采用常规熔融淬火法制备了掺Er3+的碲酸锂玻纤玻璃，并通过阻抗分析仪研究了其随温度变化的交流电导率。利用Almond-West型幂律分析了频率相关的交流电导率。电导率随频率和温度的增加而增加。得到的电导率值范围为4.092 × 10−5 ~ 3.024 × 10−5 S/cm。用相关势垒跳变(CBH)模型可以合理地推断交流电导率的机理。

Transport properties of Er3+Ions doped lithium boro bismuth tellurite glasses

Lithium boro bismuth tellurite glasses doped with Er3+ ions were successfully prepared by conventional melt quenching method and investigated their temperature dependent AC conductivity through impedance analyzer. The frequency dependent AC conductivity has been analyzed using Almond-West type of power law. The conductivity increases with increase of both frequency and temperature. The obtained conductivity values lie in the range of 4.092x10−5 to 3.024x10−5 S/cm. The AC conductivity mechanism can be reasonably inference in terms of correlated barrier hopping (CBH) model.Lithium boro bismuth tellurite glasses doped with Er3+ ions were successfully prepared by conventional melt quenching method and investigated their temperature dependent AC conductivity through impedance analyzer.
