Abstract

Lanthanum-bismuth orthoferrite (La1-xBixFeO3 with x=0.1, 0.2, 0.3, 0.4 and 0.5) nanoparticles have been successfully prepared using sol-gel method. The crystalline structure, lattice vibration, and optical energy analysis have been characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman scattering spectroscopy, and UV-Vis spectroscopy. The XRD revealed the single phase orthorhombic structure with Pnma space group. The crystallite size tends to decrease in the range of 130 - 298 nm with increasing Bicontent. The existence of Fe-O strectching and bending modes were investigated by FTIR spectra and also confirmed by Raman scattering analysis. The optical bandgap was investigated by UV-Vis spectroscopy concluding the decrease of gap energy with Bi-content.
