| Abstract | Sulfur-doped DLC nanocomposite films have been successfully deposited by the electrochemical method using the mixture of methanol and thiofuran as the precur- sor at ambient atmospheric pressure. In contrast to DLC film, the effects of sulfur incorporation on the microstruc- tural transformation and properties of sulfur-doped DLC nanocomposite films were investigated in detail in terms of atomic force microscopy, X-ray photoelectron spectroscopy, Raman spectrum and photoluminescence and magnetic tests. The experimental results showed that the unexpected organic molecular structure was formed like sulfone or thi- ols in sulfur-doped DLC nanocomposite films, and the con- centration of sulfur in films was readily manipulated by the volume ratio of thiofuran to methanol. Meanwhile, the sp3-hybridized carbon content gradually decreased in films as the volume of thiofuran increased. Furthermore, sulfur- doped DLC nanocomposite films showed the monochro- matic photoluminescence performance with a wide band centered at 510 nm, which could be attributed to carrier localization within an increasing sp2 clusters and the de- fects along with the sulfur doping. Particularly, ferro-like magnetic performance of sulfur-doped DLC nanocomposite film might originate from the magnetic moment of localized sp2 clusters with different charged carriers near the Fermi level after sulfur incorporation. |
