摘要: Abstract Recently an account of the homoepitaxial growth diamond in oxygen-acetylene combustion flame was published (J. Cryst. Growth, 104 (1990) 752). Notwithstanding high deposition rate (50 μm-1 h), material had good optical quality. After removal natural substrate from one samples, it proved that deposit single-crystal diamond. However, most properties were measured with layers still attached to substrate. In this study more elaborate characterizations free-standing, flame-grown are described. Hydrogen, nitrogen and perhaps oxygen identified as impurities, based on IR spectroscopy both photoluminescence cathodoluminescence (PL CL). The distribution impurities is non-uniform, verified by CL topography stress birefringence microscopy. Following standard classification rules neither type I nor II.
