Structural, morphological, Raman, dielectric and electrical properties of La_1−2xBa_xBi_xFeO₃ (0.00 ≤ x ≤ 0.20) compounds

Abstract

La1−2xBaxBixFeO3 (0.00 ≤ x ≤ 0.20) nanoparticles were prepared by the auto-combustion method using glycine as a combustion fuel.

LaFe1–xCoxO3 Perovskite Nanoparticles Supported on Ni(OH)2 as Electrocatalyst for the Oxygen Evolution Reaction

“…The out of phase La vibrations of A g symmetry are observed around 138 cm –1 as broader nature modes . The oxygen octahedral tilt modes of A g symmetry along with the combination of La site are assigned to the peaks located around 282 and 312 cm –1 . The oxygen octahedral bending vibration of B 2g , B 1g , and B 3g symmetry are attributed to the pair of peaks around 391, 421, and 475 cm –1 , respectively. , The asymmetric stretching vibrations with A g symmetry are considered the cause of the broad peak around 515 cm –1 , which is the Jahn-Teller distortion. , The in phase symmetric oxygen stretching vibrations of B 1g symmetry are the intense peaks in the range of 600–700 cm –1 , while the low intense phonon mode over 800 cm –1 may be due to the multiphonon processes.…”

Study of the structural, electrical, dielectric properties and transport mechanisms of Cu0.5Fe2.5O4 ferrite nanoparticles for energy storage, photocatalytic and microelectronic applications

“…These plots are characterized by semi-circular arcs whose diameter decreases with increasing temperature. The maintenance of a single semicircle at each temperature proves that the electrical mechanism obeys a single relaxation process and the decrease in diameter with increasing temperature refers to the sharp increase in the DC conductivity [ 75 ]. In order to analyse such a diagram, it is essential to fit these impedance curves using the Zview software.…”

Synthesis, characterization, and sensitivity tests of La0.8Ba0.1Bi0.1FeO3 nanoparticles towards a few parts-per-billion of acetone gas

“…The present sample was synthesized using the auto-combustion route. The synthesis details and steps were previously studied [ 27 ], where appropriate amounts of Iron nitrate Fe(NO 3 ) 3 .9H 2 O, Lanthanum nitrate La(NO 3 ) 3 .6H 2 O, Barium nitrate Ba(NO 3 ) 2 and Bismuth nitrate Bi(NO 3 ) 3 .5H 2 O were used to obtain the desired La 0.8 Ba 0.1 Bi 0.1 FeO 3 nanoparticles as shown in the following equation: …”
