Nature of SnO6 octahedron in bulk and nanoparticles of Y2Sn2O7 probed by experimental and theoretical methods

- Comparison of SnO6 octahedron in bulk and nanoparticles of Y2Sn2O7.
- XRD, 119Sn MAS NMR and Luminescence study.
- Distortion of tin environment in the nanoparticle of Y2Sn2O7.
- High electron density around Sn4+ was confirmed by NMR study and DFT calculations.
- Relatively poor transfer of charge from tin to nearby oxygen due to Sn-O bond stretching.
