Abstract

Hydrogenated amorphous silicon carbide alloys were produced by using organic carbon source, xylene, instead of generally used methane. It was found that the optical band gap of present samples is significantly increased and reaches as high as 3.1eV with increasing the xylene gas fraction to 80 percent. The film configuration was also investigated and it was shown that there exist a lot of aromatic rings in the film network. An intense blue light emission has been observed from the present samples. The luminescence wavelength is peaked in the range of 490nm to 610nm, the origin of the light emission is briefly discussed in this paper.
