Nanograpehene with an in-plane crystal size of similar to 15 nm was directly deposited on glass at 750 degrees C by thermal chemical deposition, without using any additional metallic catalyst. Annealing of nanographene film at 300 to 500 degrees C leads to an increase in the in-plane crystal size up to similar to 23 nm, when the annealing is done in the presence of an adlayer of nickel, subsequently deposited on the graphene after the initial deposition. This study clearly shows that nanographene can be directly deposited on glass and the crystallite size is controllable.
