Lattice dynamics in the phonon wing of the diamond luminescence spectrum
A model of the dynamics of the electron - phonon interaction in a diamond in the form of a second-order aperiodic link is proposed. One link characterizes the properties of optical electrons, and the other characterizes the property of the lattice. To determine the inertial parameters of the lattice, the group delay time of a sinusoidal signal in a diamond medium at room temperature was found. Natural and artificial diamonds form two independent populations in terms of delay time, which do not intersect each other. This phenomenon can find applications for the identification of cut diamonds (diamonds).
