Abstract
ABSTRACT The effect of strontium (Sr) doping on structural, morphological and optical properties of bismuth ferrite (BFO) thin films containing various doping concentrations of Bi(1−a)Sr a FeO3 (a = 0.00, 0.01, 0.03, 0.05, 0.10) was synthesized using a spray pyrolysis technique. Based on the experimental results, EDAX confirmed the existence of bismuth, ferrous and strontium particles in the developed thin films. The XRD results confirmed a decrease in the size of the crystals after Sr substitution at Bi site. The FESEM results confirmed the reduction of particle size with dopant addition. The BFO films exhibited a cone-type grain growth with an increase in surface roughness with Sr dopant. The results obtained from UV–Vis spectrophotometer show an increase in energy bandgap for various concentrations of the dopant. The results obtained from the characterization revealed that Sr-doped BFO is a very good candidate for gas sensor applications.
