Semiconducting Vanadate (V2O5 based) glass has plentiful application in the field of electrochemical batteries and optical switches. Theoretical investigation for density and molar volume are done for semiconducting glass with composition 60V2O5.(40-x) ZnO.xMoO3 (x=10,13,16,19,22). The density decreases from 4.168-4.057g/cm³ with increasing MoO3 content and an opposite behavior is observed for Molar volume. Using Lorentz- Lorenz equation index of refraction is calculated and found to be very high (4.103 to 3.920) and Oxide ion polarizability varies little in the range 2.6935- 2.6908ų. Using generalized Miller’s rule, third order nonlinear optical susceptibility found to be very high 2.39x10−6 to 1.61x10−6 esu. and Nonlinear Index of Refraction varies from 2.194x10−5 to 1.555x10−5esu.

The TEP of binary NiO-P2O5 bulk glasses of different compositions was measured. A specially design sample holder was used to measure the thermal EMF in the temperature range 303 to 530 K. The temperature difference between upper and lower surfaces maintained between 5 and 10 K. The investigations provide information on the polaron formation and the disorder energy due to random fields. The TEP found to be dependent on the NiO content and the temperature independent of TEP. Heikes’ formula for the TEP can give an adequate explanation for the experimental data. [ABSTRACT FROM AUTHOR]
