Abstract

Perovskite LaAlO3, LaAlO3:Dy3+ and LaAlO3:Dy3+:Bi3+ (1mol%) nano substance prepared through chemical combustion process using sugar as a fuel. Powder X-ray diffraction (PXRD) and transmission electron microscopy (TEM) confirmed, irregular shaped non-polycrystalline nature with Rhombohedral phase ofspace group R3m having crystallite size ranging between 24-26 nm. Scanning electron microscopy and energy dispersive spectra confirmed porous, dumbbell shaped morphology and its constituents. The FTIR peaks between 840 cm−1 to 400 cm−1 proved the presence of metal oxide and peak located at 1380.0 cm-1 ascribed to carboxylate ions vibrational modes present in the studied sample. The dielectric studies show high and increased dielectric constant for doped and codoped samples than the host sample, hence it may be used as storage devices. Cole-Cole plots for conductivity studies shows semicircles at high frequencies indicating the grain effect. There was a continuous increase in the radius of the semicircle of Cole-Cole plot, for host, doped and codoped samples indicating the increase in the resistance of the material. Therefore, the prepared material finds applications in devises like CMOS.
