Abstract

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玻璃体系电性能的影响

摘要:制备了掺杂不同浓度NiO的P2O5-ZnO-Na2O玻璃，掺杂浓度在0 ~ 6mol %之间。研究了样品在不同温度和频率下的电性能测量。发现介电常数随频率的增加而减小，电模量呈现松弛现象。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，所制备的样品表现出相关的垒跳(CBH)传导机制。结果表明，部分样品具有良好的介电性能。
