In order to investigate band gap tunability in polar oxides, we measured the optical properties of a series of Bi (Fe1-x Mnx) O3 thin films. The absorption response of the mixed metal solid solutions is approximately a linear combination of the characteristics of the two end members, a result that demonstrates straightforward band gap tunability in this system. © 2010 American Institute of Physics.
