Effect of vanadium doping on the electrical charge transport and dielectric relaxation properties of Sodium Bismuth Titanate perovskite

Structural, electrical, and dielectric study of the influence of 3.4% lanthanide (Ln3+ = Sm3+ and La3+) insertion in the A-site of perovskite Ba0.95Ln0.034Ti0.99Zr0.01O3

“…This mechanism is due to the existence of immobile charge carriers at low temperature and defects at high temperature, (ii) the maximum amplitudes of − Z ′′ decrease and move towards the higher frequencies with increasing temperature, this indicates that the relaxation process is thermally activated with an accumulation of space charge at the barrier. 66,68,83–85 Fig. 9(d) shows that the values of (− Z ′′) increase and the relaxation frequency decreases with the insertion of rare earth into the A-site of the BZT perovskite.…”

“…The value of the dielectric loss (tan δ ) is affected by structural parameters, the amount of oxygen ions transported in the material and defects (vacancies, holes, electrons,…), etc. 68 The value of tan( δ ) can be calculated from eqn (5) . It is found that the rate of increase of the loss tangent (tan δ ) is slower in the region of low temperatures, and all is constant, while for higher temperatures (above 150 °C), the value of tan δ increases sharply.…”

Role of titanate-based perovskites in solar water splitting: an overview

“…al. observed the electrical charge transport properties of sodium bismuth titanate by doping with vanadium showing highest conductivity with 15% doping material hence enhancement in photocatalytic activity [41]. The change in optoelectronic properties showing that dielectric constants of barium titanate has strongly increased due to ytterbium doping with change in electronic structure behavior was studied by Adil Alshoaibi et.…”

Lanthanide-Doped ZnO Nanoparticles: Unraveling Their Role in Cytotoxicity, Antioxidant Capacity, and Nanotoxicology

“…Only the ZLM sample exhibits an increase in the lattice parameters (after cell refinement using MDI Jade Software version 6.0). This effect can be due to the differences in the ionic radii of Zn 2+ (0.74 Å), La 3+ (1.16 Å), and Sm 3+ (0.96 Å) [23]. Some reports have shown that the face orientation of ZnO can improve its activity for H 2 O 2 generation [24].…”
