Abstract

The infrared absorption in polycrystalline diamond films deposited in oxygen-acetylene flames is characterized using the Fourier Transform Infrared Spectroscopy (FTIR). The one-phonon absorption coefficient in the region from 7 um to 12 um that is related to extrinsic defects in the diamond films shows a strong dependence on the flame conditions as well as the substrate temperature. A high degree of diamond crystalline perfection, as judged from the undetectable one-phonon absorption, is achieved under the optimized deposition conditions for our flame setup. This is further supported by the sharp Raman peak at 1332 cm−1 as well as the high purity in crystal orientation according to the x-ray diffraction pattern measured for the high quality diamond films.
