Fig. 2: PL analysis of GQD/h-BN in-plane heterostructures.
From: Blue emission at atomically sharp 1D heterojunctions between graphene and h-BN
a Schematic of the GQD/h-BN in-plane heterostructures fabricated by conversion of h-BN on Pt nanoparticles (Pt NPs). b SEM image of the GQD/h-BN heterostructures on a SiO2/Si substrate. c PL spectra of GQD/h-BN (red), Pt NPs (green), and bare h-BN (back). The PL spectrum of G/h-BN interface (blue) is the same spectrum as green one in Fig. 1d. All of samples were measured on a SiO2/Si substrate using 266-nm laser.
