Controlled Preparation

Graphene with different amounts of defects was prepared by chemical vapor deposition by controlling the flow rate of hydrogen, on which Ag nanoparticles (NPs) were deposited by magnetron sputtering.

In this work, Ag nanoparticles were deposited in the TiO[Formula: see text] nanotube films through magnetron sputtering to form Ag-TiO[Formula: see text] nanocomposite. Scanning electron microscopy (SEM) was used to study microstructure and surface morphology. Rhodamine B (RhB) was deposited on the surface of Ag-TiO[Formula: see text] substrate for Raman spectroscopy test. The size of Ag nanoparticles can be controlled by changing the magnetron sputtering time. The result indicated that sputtering for 30 s obtained the highest Raman enhancement.
