Abstract

Nitrogen (N)-doped diamond films were synthesized by resonantly exciting ammonia (NH3) molecules in ammonia-added oxyacetylene flames. A wavelengthtunable CO2 laser (spectrum range from 9.2 to 10.9 ∼m) was used for the resonant excitations. The NH wagging mode of the NH3 molecules was selected to achieve the resonant excitations. Both laser wavelengths of 10.591 and 9.219 mu;m were applied to the process. Compared with 10.591 μm produced by common commercial CO2 lasers, the laser wavelength of 9.219 μm proved much more effective in resonant excitation of the NH 3 molecules. With a 500 W laser excitation at 9.219 μm, high quality N-doped diamond films were deposited with a doping level of 1.5×1020 N atoms/cm3. A morphologic transition from amorphous cauliflower structures to columnar diamond structures was.
