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