I think it depends on the diameter of the particles you have..look also for Quantum Size Effect.. http://www.phys.hawaii.edu/~sattler/Publications/pdf-files/GapReviewPaper.pdf

The band gap of Fe2O3 is about 2.2 EV

The band gap of Fe3O4 is about 0.1 EV

doi:10.1155/2011/837123

Hamzeh Salehzadeh

but I think band gap of Fe3O4 in the range of 2.1-2.7
