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.
