Abstract

Two-color up-conversion time-resolved photoluminescence and time-resolved absorption are used to study spin relaxation of near-resonant heavy-hole excitons in spontaneously ordered (Formula presented) The photoluminescence anisotropy is studied as a function of crystal direction, revealing a strong dependence on the light orientation with respect to the ordering axis. The maximum observed polarization is 0.8, and indicates that the polarization is near unity shortly after excitation. The carrier spin-relaxation time is 150 ps.
