| Popis: | An experimental investigation was made of the deposition of amorphous diamond-like films on transparent substrates by laser irradiation of the interfaces between such substrates and liquid hydrocarbons [toluene C{sub 6}H{sub 5}CH{sub 3}, benzene C{sub 6}H{sub 6}, cumene C{sub 6}H{sub 5}CH(CH{sub 3}){sub 2}]. A copper vapour laser (wavelength 510.6 nm, pulse duration 20 ns) was used. The films were studied with x-ray Auger spectroscopy, high-energy electron diffraction, scanning electron microscopy, and Raman scattering spectroscopy. The sp{sup 3} fraction in the deposited films reached 50% - 70%, depending on the choice of hydrocarbon. The average film thickness was 100 - 200 nm and the microhardness reached 50 - 70 GPa.
