Vr. Kumar et al., EFFECT OF DC FIELD AND X-RAY-IRRADIATION ON DIELECTRIC-PROPERTIES OF ZNF2-PBO-TEO2 GLASSES, Physica status solidi. a, Applied research, 147(2), 1995, pp. 601-610
Dielectric constant epsilon, loss tan delta, and conductivity sigma of
ZnF2-PbO-TeO2 glasses (composition 20, 12, 68 by wt%), subjected to X
-ray irradiation for 1 h in the presence of a dc field up to 15 kV cm-
1, are measured in the frequency range 2 x 10(2) to 10(7) Hz and in th
e temperature range 30 to 200-degrees-C. The space charge and dipolar
effects observed from this study are discussed in the light of point d
efects created in these glasses.
