| Abstract: | As a repeating well and cheaper enhancement substrate, the nickel film was fabricated with magnetron sputtering coating instrument.
Surface enhanced Raman spectra (SERS) of pyridine adsorbed on this nickel film are compared with the experimental values of
gaseous pyridine, the theoretical value of pyridine solution listed in other literatures and our method is better than electro-chemical
etching electrode method for large scale preparation. The enhancement factor of the nickel film is calculated and the result
indicates that magnetron sputtering coating technology is feasible for obtaining good SERS active surface. |
