Structural phase transition, grain growth and optical properties of uncompensated Ga-V co-doped TiO2
Nasima Khatun, Saurabh Tiwari, Jayanti Lal +4
Effect of uncompensated Ga-V co-doping on structural phase transition, grain growth process and optical properties of TiO2 is reported here. Inhibition of phase transition due to c…
Structural, dielectric and ferroelectric studies of thermally stable and efficient energy storage ceramic material: (Na0.5-xKxBi0.5-xLax)TiO3
Anita Verma, Arun Kumar Yadav, Nasima Khatun +7
The structural, dielectric and ferroelectric properties of lead-free (Na0.5-xKxBi0.5-xLax)TiO3 powders synthesized by sol-gel self-combustion method were investigated. Rietveld ref…
Optical Property Study of Charge Compensated (Si, Na) Co-doped ZnO
Tulika Srivastava, Gaurav Bajpai, Gyanendra Rathore +4
ZnO is co-doped with Na+ and Si4+ in the ratio 2:1. The ratio was intentionally chosen so that net valence state of dopant theoretically matches that of host. This is to avoid depe…
(Pb1-xBix)(Ti1-xMnx)O3: Competing mechanism of Tetragonal-Cubic phase on A/B site modifications
Arun Kumar Yadav, Anita Verma, Birender Singh +8
Structural, vibrational and dielectric properties of (Pb1-xBix)(Ti1-xMnx)O3 (PBTM) (0 x 0.50) polycrystalline ceramics have been examined as a function of temperature. Synchrotron-…
Investigation of La and Al substitution on the spontaneous polarization and lattice dynamics of the Pb(1-x)LaxTi(1-x)AlxO3 ceramics
Arun Kumar Yadav, Anita Verma, Sunil Kumar +6
The phase purity and crystal structure of PLTA samples (synthesized via sol-gel process) were confirmed using synchrotron x-ray powder diffraction (wavelength, lmbda= 0.44573 A. Ri…
