Abstract Polycrystalline diamond films have been deposited on ceramic alumina substrates by microwave plasma chemical vapor deposition method. Variation of the emission spectra in the microwave plasma with the microwave power and the vapor pressure in the reaction chamber is studied, respectively. Relationships between the hydrogen atomic spectra and the average energy of the electrons in the plasma, as well as the mechanism of diamond film deposition on ceramic alumina are discussed.
