Measurements are presented of the electroreflectance spectra of CdS and CdSe single crystals. Comparison with the photon energies of the interband edges and exciton peaks demonstrates that the low‐energy peak of the spectra is dominated by exciton quenching. At higher energies field‐influenced interband transitions are also important at room temperature.
