用交流阻抗谱和电动势测量研究了Ag-x（GeSe 3）（1-x）（0 ≤ x ≤ 0.571）玻璃的电学性质。随着银浓度的增加，总电导率在x = 0.3左右从10（-14）S/cm急剧增加到10（-3）S/cm。这种快速增加主要是由于银离子迁移的出现。玻璃化转变温度在x = 0.33处显示出最小值，高于该最小值，粉末X射线衍射中的第一尖锐衍射峰减小。这种不寻常的过渡支持渗滤假说的光溶解的银在这些玻璃。(C)1999年由Elsevier Science B. V.出版，版权所有。
Electrical properties of Ag-x(GeSe3)(1-x) (0 less than or equal to x less than or equal to 0.571) glasses were investigated by impedance spectra and EMF measurements. As the concentration of silver is increased the total electrical conductivity steeply increases from 10(-14) S/cm to 10(-3) S/cm at about x = 0.3. This rapid increase is chiefly due to an appearance of silver ion migration. Glass transition temperature showed a minimum at x = 0.33 above which a first sharp diffraction-peak in powder X-ray diffraction diminishes. This unusual transition supports a percolation hypothesis on photo-dissolution of silver in these glasses. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
