Abstract

Optical properties of Diamond-like Carbon Thin Films deposited by DC-PECVD are reported. The films were deposited on the corning glasses with the ratio of Hydrogen, H2 (97%) and Methane, CH4 (3%) and grew diamond like carbon (DLC) thin films with different temperatures up to 873K. The other important variables were fixed such as DC voltage (1.5 kV) and pressure (1 x 10-1 torr). From the light transmission using UV-Vis spectroscopy it was found that the type of optical transition is allowed indirect transition in the range of 3.8eV to 4.3eV. The thickness decreases with the increases of substrate deposition temperature. The photoluminescence analysis was order to obtain the peak of excitation and emission range of the sample films. It has been found that the transition energy in the range of 3.06 to 3.22 eV.
