agrees with the past report [7].The obtained direct bandgap 2.68 eV of the epitaxialBFO thin film is comparable to 2.74 eV reported in BFOnanocrystals [31] but is larger than the reported 2.5 eVfor BFO single crystals [32].

This is because small part of the scattered incident radiation combines with the primary incident wave resulting in phase change that is tantamount to alternation of the wave velocity in the thin film medium.
