Abstract

It is determined experimentally that the luminescence spectrum of a diamond at room temperature contains one or two Gaussian peaks. This result is associated with the exciton–phonon interaction in diamond, which, along with the zero-phonon line, contains phonon repetitions of the first and second order. This phenomenon is characteristic only of natural diamonds and is absent in synthetic samples. Therefore, it can be used to identify cut diamonds.
