HR-TEM images of e-GOQDs and h-GQDs. a TEM image of e-GOQDs and b h-GQDs. They both showing the uniform round shape and size distribution of 1 ~ 5 nm. Scale bar 50 nm. c HR TEM image of e-GOQDs and d h-GQDs. Insets are the 2D FFT patterns (left). They both show high quality crystalline hexagonal patterns of these quantum dots. Scale Bar 5 nm. Right side insets show the edge structure of e-GOQDs and h-GQDs. Scale bar 2 nm
