Анотація | Optical density spectra of amorphous diamond-like films of hydrogenated carbon modified with platinum impurity (a-C : HPt) have been investigated. a-C : HPt films were prepared by the method of ion plasma magnetron co-sputtering of graphite and platinum in argon-hydrogen atmosphere. Platinum content in the films was varied from 0 to 9 at. %. In the optical spectra of a-C : HPt films with different Pt content the peaks of resonance absorption in the range from 496 to 501 nm were found, whilst in the spectrum of a-C : H films the absorption peak is absent. The appearance of these absorption peaks in a-C : HPt films is explained by resonance plasmon vibrations of free electrons in platinum nanoclusters. The average diameter of the Pt nanoclusters was estimated using electromagnetic theory of Mie, and it is ~ 5 nm. |
