Pure and Rare Earth transition metal (7.5% and 10% lanthanum, yttrium) doped bismuth ferrite samples were synthesized through chemical solution route. Crystallization temperature around 450°C was observed from thermal analysis by DTA-TGA and subsequent XRD analysis of the annealed samples showed that the crystallites were mainly rhombohedral with R3c space group with an expected impurity phase. Morphological analysis using FESEM and AFM revealed the samples to be of agglomerated nature and optical analysis by UV-VIS spectroscopy showed a decrease and increase in the band gap due to La and Y doping respectively.

Keywords: La/Y doped BFO, DTA-TGA, XRD, FESEM, AFM, UV-VIS etc.
