Abstract

Exciton lifetimes in Cdi-xMnxTe-CdTe superlattices (x = 0.06, 0.23 and 0.45) at 7 K have been studied by time-correlated single photon counting with high spectral resolution. The lifetimes decrease with well thickness, in agreement with earlier spectrally integrated luminescence decay measurements using a spectrometer/streak camera combination. Our spectral resolution is sufficient to show small structure for the Cd0.5Mn0.45Te-CdTe sample at energies near those predicted by a Kronig-Penny calculation for the subbands, and we report the time behavior of these states.
