Bismuth and zinc co-doped Y2O3 samples are synthesized by sol-gel method using ammonium hydroxide as a precipitating agent. Structural analysis is done by XRD, SEMEDAX and the optical properties are analysed by FTIR, UV-Vis absorption studies and photoluminescence (PL) studies. UV-Vis absorption studies show absorption only around 340 nm whereas PL shows peaks around 401 nm, 680 nm and 1020 nm ...

Recent theoretical studies employing density-functional theory have predicted BaBiO3 (when doped with electrons) and YBiO3 to become a topological insulator (TI) with a large topological gap (~0.7 eV). This, together with the natural stability against surface oxidation, makes the Bismuth-Oxide family of special interest for possible applications in quantum information and spintronics. The centr...

in this work, the strontium-doped lanthanum manganite- a ceramic material- used as cathode in solid oxide fuel cells. an impression of grinding time on the structural and thermal properties of sr-doped lamno3 system with la1-xsrxmno3 (x=0.2) stoichiometric ratio was investigated. the nano crystallite lsm powder with cubic structure was prepared by varying the milling time of planetary monomill ...

This study presents bismuth ferrite nanoparticle (BFO) modified carbon paste electrodes (BFO/CPEs) for the determination of lead and cadmium.

We use density functional theory to identify several previously unknown polar and nonpolar structures within the low-energy phase space of perovskite-structure bismuth ferrite, $\mathrm{Bi}\mathrm{Fe}{\mathrm{O}}_{3}$. Bismuth ferrite is one most widely studied multiferroic materials because its large ferroelectric polarization coexisting with magnetic order at room temperature. Of particular i...
