Dear Bharani Dharan,

The estimated band gap of Fe3O4 "magnetite" (2.2 eV) which is slightly higher than the bulk iron oxide (2.0 eV) due to less in size.

Naveen Kumar J R

The Bandgapgap of Fe3O4 is ∼0.10eV. @Bharani Dharan

A. Muthuvel

The estimated band gap of magnetite NPs we obtained is (2.2 eV) which is slightly higher than the bulk iron oxide (2.0 eV) due to less in size.
