Abstract

Time correlated single-photon-counting is a high-sensitivity high-resolution spectroscopic method for picosecond photoluminescence which we apply to two important II-VI semiconductors. In crystalline bulk Cd1-xZnxTe we measure lifetimes of impurity-bound excitons and relate them to theory. In Cd1-xMnx-CdTe superlattices we measure lifetimes of confined excitons decreasing with well thickness, which we relate to two-dimensional behavior, and find lifetimes possibly associated with subband energies.
