Abstract

The work presented in this thesis described the structural, optical and transport properties of some oxide and non-oxide (chalcogenide) glasses containing transition metal ions. The glass samples under study were prepared by standard melt-quench technique. The following glass systems were prepared and studied during the present work.
(i) xFe2O3.(40-x)PbO.60B2O3 {FPB glasses}
(x = 0, 4, 8, 12, 16 and 20 mol %)
(ii) xMoO3.(40-x)PbO.60B2O3 .yV2O5 {MPBV glasses}
(y = 0 and 2; x = 0, 2, 4 and 6 mol %)
(iii) xFe2O3.(40-x)Bi2O3.60B2O3 .yV2O5 {FBBV glasses}
(y = 0 and 2; x =0, 4, 8, 12, 16 and 20 mol %)
(iv) xMoO3.(40-x)Bi2O3.60B2O3 .yV2O5 {MBBV glasses}
(x = 0, 2, 4 and 6; y = 2 mol %)
(v) Se (72 - x) S28 Znx (x = 0, 2, 4) {ZSS glasses}
(vi) Se (96 – y) Sy Zn4 (y = 20) {ZSS glasses}
The above glass systems were chosen in order to study the effect of addition of transition metal (TM) ions in PbO-B2O3, Bi2O3-B2O3 and Se-S glass systems. Two types of TM ions were chosen in oxide glasses, Fe and Mo. In order to study the effect of mixed TM oxides, V2O5 was added to MPB, MBB glasses (to form MPBV and MBBV glass systems) and FBB glasses (to form FBBV glass system). Most important result is that the DC conductivity is found to increase with increase in TM ion (s) in FPB, FBB, MBB and ZSS glasses whereas it decreases with increase in TM ions in case of MPBV (y = 0 and 2) glasses The results obtained from present studies (i.e. above glasses) have been compiled in the form of the thesis, the contents of which are divided into six chapters.
