We report the low-temperature photoluminescence and its excitation spectra of GaAs/Al0.32Ga0.68As Bragg confining structures. The spectra of these structures, which consist of short superlattice sections separated by Al0.32Ga0.68As spacer layers, are compared with those of conventional superlattices. The energies of the observed optical transitions between the Bragg confined levels (localization on the spacer layer) are in a good agreement with calculations, based on the Kronig-Penney model for the envelope functions of the electrons and holes.
