摘要: We develop a quantitative theory of the ratio R radiative to non-radiative de-excitation based on Dexter-Klick-Russell criterion for occurrence luminescence. The model invokes three essential elements: promoting mode, an accepting and set lattice modes which ultimately absorb vibrational energy. is determined by relative population relaxed excited ground states. show that Rnx(a)/ng(a), where nx(a) ng(a) are numbers quanta in mode associated with state state, respectively, at crossing their adiabatic potential energy curves. result consistent experiment.
