Abstract
AbstractThe results of studies of the structure and properties of composite materials based on amorphous carbon ( a -C:H) films and tin nanoparticles are reported. The composite films are synthesized by the magnetron-assisted ion-plasma sputtering of a combined target in a 92%Ar : 4%CH_4 : 4%H_2 gas mixture. The dependence of the local structure of the a -C:H〈Sn〉 films on the conditions of synthesis and the content of Sn nanoparticles is clarified by means of Raman spectroscopy. The dependence of the photoluminescence intensity and the optical band gap of a -C:H〈Sn〉 films on the Sn content is shown.
