Transport phenomena and conductivity mechanism in Sm doped Bi4V2−xSmxO11 ceramics

Structural, Micro-Structural and Electrical Properties of Rare Earth Doped Bi4V2O11Ceramics

“…It is observed that the samples (x = 0.05-0.10) are exhibited characteristic doublet at 2θ ≈ 32 • and singlet at 2θ ≈ 46 • , which suggests the presence of the β phase orthorhombic crystal structure at room temperature. Moreover, the presence of two double peaks at 2θ ≈ 32 • , 46 • suggests the presence of the α-phase monoclinic crystal structure 17. A good agreement between observed (obs) and calculated (cal) interplanar spacing d ( d = d obs -d cal = minimum) is obtained.…”

“…16 Bag et al studied the transport phenomena and conductivity mechanism in Sm doped Bi 4 V 2-x Sm x O 11 ceramics. 17 We have, recently, reported AC impedance spectroscopy z E-mail: banarjibehera@gmail.com and conductivity studies of Dy doped Bi 4 V 2 O 11 ceramics. 18 We have also worked on other rare earth (Sm and Dy) doped Bi 4 V 2 O 11 and published elsewhere.…”

“…18 We have also worked on other rare earth (Sm and Dy) doped Bi 4 V 2 O 11 and published elsewhere. 17,18 To understand the effect on electrical properties of Bi 4 V 2 O 11 , we have chosen Nd dopant as compared to other rare earth element (Sm and Dy). In view of the above, the present paper reports the synthesis, structural, micro-structural and electrical properties of layered bismuth oxide structure compounds of Nd doped Bi 4 V 2-x Nd x O 11 (x = 0.05-0.20) ceramics.…”
