Abstract

The shape of emission bands is determined by the vibrational-energy distribution of the luminescence centers and by the form of the potential curves. A new potential is introduced, permitting us to establish the intensity distribution within a band as a function of frequency and temperature. The calculations are based on a semiclassical approximation of the Franck-Condon factors and are worked out with the aid of the Mehler formula. The obtained expression is in close agreement with the experimental results.
