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

10 October 2018 0 1K Report

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 incorporation.
