Figure 2: Structural characterization of SNPs, GQDs, and SNPs/GQDs hybrid.

From: Energy transfer from an individual silica nanoparticle to graphene quantum dots and resulting enhancement of photodetector responsivity

Figure 2

(a) LRTEM and HRTEM images of SNPs. The SNPs are shaped like spheres of about 300 nm average diameter. (b) LRTEM image of GQDs and HRTEM image of a single GQD. The GQDs of ∼12 nm size were used in the FRET system. (c) HRTEM image of a single SNP. (d) HRTEM image of a single SNP coated with GQDs. (e) HRTEM image of GQDs sitting on the surface of a SNP. (f) EELS spectra of a SNP, a GQD, and a SNP/GQDs hybrid in the C and O K-edge regions.
