Abstract
A theoretical study is made of the effect of Raman scattering of light in crystals on their exciton luminescence. The polariton concept is used to show that Raman scattering may play a determinative role in the low-temperature luminescence of excitons with a large oscillator strength. The luminescence spectrum calculated on a computer by the Monte Carlo method is in good agreement with experimental data. This enables a number of experimental facts concerning the luminescence of crystals at low temperatures to be ascribed to the influence of Raman scattering.
