| Abstract: | Results of an optical study of heterostructures based on new compounds, ZnSe/ZnMgSSe, are presented. The possibility of using
these compounds to produce high-quality quantum-well structures having strong exciton features in optical spectra is demonstrated.
An analysis of reflectance spectra has yielded the exciton parameters: the resonant frequency, oscillator strength, and exciton
line damping. The exciton binding energies have been determined from magneto-optical spectra. The samples studied have a high
structural perfection and small inhomogeneous width of the excitonic resonances.
