Abstract
Using the conventional melt-quench technique, a glass system of specific composition 20ZnO- (28-x) Te2O3-52B2O3: x mol% MnO where 'x' varies from 0.5 to 2.0 was synthesized. All the prepared glass samples were examined for their solid-state behavior by XRD and SEM those confirm the non-crystalline state. In this work, three important dielectric properties were experimentally measured across 1 to 100 kHz frequency and room temperature to 200oC range. These parameters show an increasing trend with dopant which confirms the growing degree of disorder due to trivalent manganese ions that acted as modifiers with large concentrations. However, the reasons for variation in activation energy including other dielectric parameters are discussed in detail through the oxidation states of manganese ions and their structural changes.
