Abstract

Background

Barium Titanate (BaTiO) is a good candidate for a variety of applications due to its excellent dielectric, ferroelectric and piezoelectric properties.

Methods

Pure and doped Barium Titanate (BTO) nanoparticles have been synthesized by the sol-gel method. Barium hydroxide octahydrate (Ba (OH).8HO) and titanium (IV) iso-propoxide (Ti {OCH[CH]}) were used as starting materials. Apart from pure Barium Titanate nanoparticles, Fe-doped BaTiO nanoparticles of three different concentrations: 0.1, 0.2 and 0.3 in mol% were prepared and characterized using X-ray diffraction (XRD), UV visible spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR).

Results

From the X-ray diffraction pattern, the particle size was found to be varied in a range of 17-25nm. By using UV visible spectroscopy it was observed that the band gap energy of pure BaTiO NP is 3.2eV. As the pure BaTiO nanoparticles are doped with 0.1% Fe, the band gap reduces to 3.175eV. For BaTiO doped with 0.2% and 0.3% Fe, the band gap energy values are 2.709 and 2.652 respectively. FTIR spectra were used to analyze the vibrational modes of BaTiO. From the result obtained from FTIR, we can see that the absorption spectrum ranges from 450 cm-1-4000 cm-1. The prominent peak of pure BaTiO is at 500 cm-1 which is due to the vibration of the Ti-O band in crystal lattice. For BaTiO doped with FeO, the wave number of the absorption peak is shifted from 500 cm-1 in pure BaTiO. The antibacterial studies were conducted on , and .

Conclusion

Both pure and Iron-doped Barium Titanate showed significant antibacterial properties, confirming the antibacterial property of Barium Titanate nanoparticles.
