Effect of graphene oxide (GO) nanosheets incorporation on band gap of PVA is noticed very small, can any one explain this?

Direct band gap of PVA (5.3 eV) was reduced to 4.7 eV after incorporating 0.5 wt% GO nanosheets. Whereas, for indirect band gap this effect was significant (4.9 eV to 2.9 eV) for the same...
