| Four-single quantum wells composed of the ternary non-magnetic compounds Cd0.93Zn0.07Te (well width = 13, 19, 40, 90 Å), separated by the quaternary magnetic-compound Cd0.48Zn0.04Mn0.48Te on (100)GaAs substrate were grown by MBE, and exhibited clear and distinctive photoluminescence lines corresponding to each quantum well. Double luminescence peaks with closely spaced within one well were observed from 90 Å and 40 Å quantum wells. Temperature and magnetic-field study revealed characteristic luminescence features associated with a bound exciton near the interface rather than with one monolayer fluctuation. |
