We have investigated the optical properties of high‐quality ZnSe crystals grown by the recrystallization method through optically detected cyclotron resonance (ODCR). ODCR signals are observed by scanning the photoluminescence (PL) wavelength or the applied magnetic field. ODCR as a function of the PL wavelength shows positive and negative signals, which means an increase and a decrease in PL intensity due to cyclotron resonance. It was found that some ODCR spectra obtained as a function of the magnetic field consist of two peaks. We compare the ODCR spectra with an ordinary cyclotron resonance spectrum and discuss the relationship between these spectra. It was made clear that the peak positions of ODCR signals are different from that of the ordinary cyclotron resonance.
