Abstract
Graphene oxide quantum dots (GOQDs) have drawn much attention for their modulated bandgap rendering their application in optoelectronic devices. In this study, we present comprehensive photoluminescence properties of GOQDs and its related optical transitions, which agree with recent theoretical predications. In particular, ormosil gel glasses doped GOQDs was synthesized to achieve tunable photoluminescence. We also report the third-order nonlinear optical properties of the quantum dots, which were studied by using Z-scan technique. The evaluated one-photon and two-photon figures of merit demonstrate that GOQDs could be a promising candidate for the optical switching applications in a broad wavelength region.
