Structural, microstructural and optical investigations of (Bi0.5Na0.5) TiO3-LaFeO3 system

The polycrystalline samples of (((Bi 0.5 Na 0.5 ) 1−x La x )(Ti 1−x Fe x )O 3 ) (BNTLF) with x = 0.0, 0.1, 0.2, 0.3, 0.4 and 0.5 system were prepared using a solid-state reaction technique. The formation of the desired materials and their structural properties were carried out by using the X-ray diffractions. Field Emission Scanning electron microscope confirms the polycrystalline nature of the samples contains uniform grain distribution of unequal size and EDX analysis confirmed the degree of doping. Transmission electron microscopy image shows the particle size. The presence of functional group was confirmed by Fourier transform infrared spectroscopy. The dominant bands in the Raman spectra are analyzed by observing the changes in their respective peak position, width and intensities as the x increases.
