ABSTRACTData about fast luminescence of natural and synthetic diamonds are presented. Analysis of the luminescence spectra and the kinetics of both the luminescence and pulse conductivity leads to the conclusion that these processes are determined by the band electron lifetime.

Natural and synthetic diamonds with various concentrations and types of point and extended defect were investigated using X-ray topography employing allowed (111, 004) and forbidden (222) reflections. On the topographs of the forbidden reflections, weak stress fields from lattice imperfections and extended defects are readily observed. Comparison of the topographs with IR maps of the distribution of point defects suggests that certain types of point defect may increase the structure factors of the forbidden reflections.
