Optimization of Immobilization of Nanodiamonds on Graphene
We report using simple dip-coating method to cover the surface of graphene with nanodiamonds for future optical detection of defects on graphene. Most important part of the immobilization process is the pre-functionalization of both, nanodiamond and graphene surfaces to obtain the selectiveness of the method. This work focuses on an example of using electrostatic attraction to confine nanodiamonds to graphene. Raman spectroscopy, micro-luminescence imaging and scanning electron microscopy were applied to characterize obtained samples.
