Pr-doped BiFeO₃ thin films growth on quartz using chemical solution deposition

Abstract Bismuth ferrite (BiFeO 3 ) is an interesting multiferroic material due to its ferroelectric properties at room temperature. In this study, Bi 1− x Pr FeO and BiFeO films were grown on quartz substrates by the chemical solution deposition method 600 o C of annealing Variation in molar concentration was set ( = 0.03, 0.05, 0.1, 0.2) investigate their crystal structure optical characteristics. examined using X-ray diffraction (XRD) ultraviolet (UV)-vis spectrophotometer. The XRD results demonstrated that addition shifted angle smaller angles so it reduced lattice constant. Besides, size declined with more numbers, while strain expanded. UV-vis characteristics measured wavelength range 200–800 nm. transmittance values Pr-doped increased. Because doping, refractive index decreased energy dispersion
