摘要：

Circularly polarized excitation light produces spin-polarized excitons in long-range ordered Ga0.5In0.5P, because of a splitting at the valence-band maximum. We observed the spin relaxation process in ordered Ga0.5In0.5P under resonant excitation of heavy-hole excitons. The circularly polarized exciton luminescence shows a maximum anisotropy of about 35%. The decay profile of the depolarized luminescence is described by two components; the rapid decay by exciton-relaxation processes and the slower exciton recombination. An excitonic spin-relaxiation process occures during the initial rapid decay.
