Structural analysis of nanostructured iron antimonate by experimental and quantum chemical simulation and its LPG sensing

- FeSbO4 having minimum crystallite size 2 nm was synthesized by sol-gel process.
- Rietveld method and vibrational spectroscopy confirmed size and other properties.
- SEM, XRD, UV, DSC, FT-IR and Raman spectra characterized the material.
- First combined experimental and theoretical study on vibrational properties.
- Significant advancement towards the fabrication of robust gas-sensor.
