Tomozeiu, N and Seekamp, J and Ferrari, A and Niemann, J (2000) On the photoluminescence of a-C:H films. Journal of Optoelectronics and Advanced Materials, 2. pp. 241-246. ISSN 1454-4164Full text not available from this repository.
a-C:H films deposited from methane and helium mixture in a capacitively coupled rf plasma were found to show photoluminescence (PL) with peak intensities at energies far above the Taue gap of these films. Apart from the PL the films were investigated with respect to their IR and UV/VIS absorption properties as well as their Raman spectra were examined. The ultraviolet (UV) and blue luminescence from hard a-C:H thin films are explained by incorporation of polycyclic hydrocarbons from gas-phase reactions in the methane helium plasma into the film.
