Abstract

Perovskite-type La-doped Yttrium Chromite (Y1–XLaxCrO3) nanoparticles are prepared via sol–gel method. The formation of the compound is confirmed by X-ray diffraction (XRD) technique. Particle sizes are calculated by Transmission Electron Microscopy (TEM) measurements. Electrical DC conductivity is studied. DC conductivity analysis shows that all the samples have semiconducting behavior. Dc activation energy decreases when the lanthanum doping content is increased. The dielectric properties of all the samples are studied within the temperature range 298–523 K and in the frequency range 20–1 MHz. Impedance (AC) analysis suggests that the assistance of grain boundary governs over the grain.
