Chemically modified graphene oxide (GO) sheets exhibit "fingerprinting" photoluminescence (PL), which originates from the [sigma]* [rightward arrow] n, [small pi]* [rightward arrow] [small pi] and [small pi]* [rightward arrow] n electronic transitions between the antibonding and the bonding molecular orbitals. These three PL peaks exhibit a red-shift with an increase in the excitation wavelength.

Formation of the composite containing 10 wt% of mildly oxidized GO and 90% MnO2 results in an improvement in the capacitance (18 times in Li2SO4 and 60 times in Na2SO4) as compared to that measured on MnO2. Addition of highly oxidized GO is not favorable owing to the defects in the layers that limit conductivity and charge propagation.
