TEM images of 0.2OH-GQD@Si/0.2rGO-1 (a, c, e) and 0.3OH-GQD@Si/0.1rGO-2 (b, d, f) at different magnifications demonstrating individual lattice spacing assigned to Si, OH-GQD, and rGO (e, f). High crystallinity was verified by the SAED image (g) and representative FFT pattern (h inset) of 0.3OH-GQD@Si/0.1rGO-2.
