Paper Abstract

The composite films of c and SiO2 were fabricated by an rf co-sputtering technique and post-annealing treatment, strong PL spectra with a peak energy about 2.22 eV was obtained at room temperature. We investigated the PL spectra dependence on substrate temperature annealing temperature, and sample thickness. Using Raman scattering, IR transmission and XRD measurements, we studied the structures of the composite films. Some results were discussed.
