Role of oxygen interstitials in Zn1-xGaxO for faster response to UV light
Prashant Kumar Mishra, Tulika Srivastava, Saniya Ayaz +3
ZnO doped with Gallium (Ga3+) demonstrates better crystalline nature and conductivity increases. Latent defect states are suppressed. However, due to the larger charge of Ga3+ oxyg…
Rare earth size dependence on structural, electronic and magnetic properties of R2NiMnO6 double perovskites
Mohd Nasir, Sunil Kumar, N. Patra +8
Rare earth Manganite Nickelite double perovskites are prepared by solgel assisted combustion route, where, R varies from La, Pr, Nd, Sm, Gd, Tb, Dy, Y, and Ho. The samples have bee…
Defect mediated changes in structural, optical and photoluminescence properties of Ni substituted CeO2
Saurabh Tiwari, Gyanendra Rathore, N. Patra +7
Local and long range structure, optical and photoluminescence properties of sol-gel synthesized Ce1-xNixO2 nanostructures have been studied. The crystal structure, lattice strain a…
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-…
