We report on a study of photoluminescence from CdTe quantum wells (QW) surrounded by Cd1-xMnxTe barriers. Previous investigations of this QW system were limited to the Mn molar fraction x in the barriers not exceeding x approximate to 0.3, Here, the study includes samples in the entire range of the molar fraction 0.1 < x less than or equal to 1. The width of the investigated quantum wells ranged from 4 ML (similar to 13 Angstrom) to 30 ML (similar to 100 Angstrom). We report also on the temperature dependence of the PL line position. The luminescence persists up to room temperature evidencing a good quality of the samples even in the case of very deep QW, i.e. for wells and barriers differing significantly in their lattice parameters. Finally, we compare the observed PL energies from quantum wells with different x with calculations based on the envelope function method assuming a square-well potential. The excitonic effect and the effect related to internal strains are taken into account. The scatter of the data does not exceed that expected for QW width fluctuation and/or interface Mn interdiffusion by +/- 1 ML.
