Solid-state quantum emitters, in particular color centers in diamond such as nitrogen-vacancy (NV) centers, are promising candidates for single photon sources. We provide an elementary description of the dynamics of defect centers in terms of a quantum optical master equation which includes spontaneous decay and a simplified vibronic interaction with lattice phonons [1]. We present the general solution of the dynamical equation by means of the eigensystem of the Liouville operator and exemplify the usage of this damping basis to calculate the dynamics of the electronic and vibrational degrees of freedom and to provide an analysis of the spectra of scattered light. The dynamics and spectral features are discussed with respect to the applicability for color centers, especially for NV centers.
