A Raman spectroscopic investigation of graphite oxide derived

The ball-milling procedure breaks the large crystallites into smaller particles and also introduces significant amount of defects as can be seen from Fig. 1 b . The 2D band changes from a two peak profile to a single peak after ball-milling for 12 h. After 24 h the 2D band is suppressed and a bump like region emerges similar to that observed in FLwGs. Since no chemical treatments were given the peculiar 2D band shape cannot be due to functional groups and must be due to
