Abstract P2O5–ZnO–Na2O glasses doped with various concentrations of NiO in the range from 0 to 6 mol % are prepared. The measurements of the electric properties of the samples are studied at different temperatures and frequencies. It is found that the dielectric constant decreases with increasing frequency as well as the electric modulus shows relaxation behaviour. The effect of different NiO concentrations and their chemical states in the glass network appears in the analysis of the activation energy, where Ni2+ ions have octahedral and tetrahedral states. From the frequency exponent result, the present samples exhibit correlated barrier hopping (CBH) conduction mechanism. The results show that some samples have great dielectric properties.

镍离子对P2O5-ZnO-Na2O玻璃体系电行为的影响

摘要 P2O5-ZnO-Na2O 玻璃掺杂了不同浓度的 NiO，范围从 0 到 6 mol%。在不同温度和频率下研究样品的电特性的测量。发现介电常数随着频率的增加而降低，并且电模量表现出松弛行为。不同 NiO 浓度及其在玻璃网络中的化学状态的影响出现在活化能分析中，其中 Ni2+ 离子具有八面体和四面体状态。从频率指数结果来看，本样品表现出相关的势垒跳跃（CBH）传导机制。结果表明，一些样品具有很好的介电性能。
