The emission spectrum of the zero-phonon n = 1 A exciton line in CdS crystals has been investigated for temperatures in the range 2 to 25 K with high resolution and compared with the polariton dispersion curve which has heen measured experimentally. It has been found that the resonant exciton luminescence arises from the emission of polaritons of the lower branch of the polariton dispersion curve. The emission line consists of two maxima, one being connected with the “knee” of the polariton dispersion curve and the other arising from the anomaly in the crystal boundary transparency.
