Modifications of exciton and trion photoluminescence and photoluminescence excitation spectra have been studied in modulation‐doped CdTe/(Cd,Mg)Te quantum well structures as a function of electron concentration and magnetic fields. These modifications have been explained in terms of combined exciton–electron processes.
