Abstract
Boron doped and undoped diamond films were prepared by a hot filament method of chemical vapor deposition (CVD). Up to 1020 cm-3 boron concentration was obtained in doped specimens. Infrared (IR) absorption and luminescent emission of diamond films were measured and discussed. Absorption peaks of 1971.3 cm-1, 2020.0 cm-1, and 2161.4 cm-1 were observed in undoped diamond films, which are assigned to two-phonon lattice vibration absorption of diamond. Two absorption peaks at 2850 cm-1 and 2910 cm-1 were usually observed in CVD diamond films, which is very similar to that of C-H vibration absorptions in CH2-radicals. In the range of 300 nm - 800 nm, four typical luminescent emissions were observed, which are 2.76 eV broad emission, 2.34 eV broad emission, 2.16 eV sharp emission with a low- energy shoulder and a sharp emission at 1.675 eV. The 2.34 eV emission is originated from the donor-acceptor (D-A) pairs, the others are originated from defect related centers.
