摘要
Magnetron sputtered diamond-like carbon(DLC)films were irradiated by cw CO_(2) laser.It was found that the laser irradiation increased the visible absorption,decreased the optical gap of DLC and decreased lightly the infrared transmittance.The absorption curves of the as-deposited and the irradiated films indicated that the irradiation decreased the hydrogen content and the sp^(3) hybrid structure and altered the absorption mode of C-CH_(3).
