Ultra-violet Photodetection, Photoluminescence and Energy Storage Properties of LaMnO3 3 and BiFeO3 3 Doped BaTiO3 3 - A Multifunctional Nanoceramic

BaTiO3 3 (BTO) is modified by 10 % (mole) BiFeO3 3 (BFO) and LaMnO3 3 (LMO) each via a chemical process. Thermogravimetric analysis (TGA) of the precursor mass, X-ray diffraction study (XRD), and scanning electron microscopy (SEM) is performed for the determination of calcination temperature, crystallographic phase, structure, and morphology respectively. FTIR spectroscopy is used for the recognition of peaks to identify the elements due to structural modifications by doping. A diffusive reflectance spectrum (DRS) study shows a band gap of Eg g 2.6 eV. Photoluminescence study shows the presence of the material in the violet, green, and blue zones. A detailed investigation of structural, micro-structural evolution, electrical, magnetic, and optoelectronic properties are performed. The resistivity study reveals the distinct nature of the material that behaves as a semiconductor up to the transition temperature (105.5 degrees C) and then as a conductor below that point. The very small amount of doping enhances the magnetism and made it higher than LaMnO3. 3 . 71 % energy storage efficiency is observed at field intensity 1500 V applied voltage with low leakage current density. Furthermore, a photoresponsivity of 17 mA/W is observed under 365 nm ultraviolet light illumination at a remarkably low bias condition (1 V) for this sample.
