Time-resolved photoluminescence and pumpprobe spectroscopies have employed study the spin relaxation processes of excitons in bulk semiconductors and semiconductor quantum- wells (QWs). Extensive studies have shown that the spin dynamics in QWs quite differs from that in bulk.1 In spite of many studies on excitons with large Bohr-radius such as in GaAs-based QWs,2 studies on excitons with small Bohr-radius is lacking. Since a spin relaxation greatly depends on the exchange interaction between electron and hole in the exciton, the spin dynamics is expected to change with the coupling strength between electron and hole. Therefore, experiments for excitons with small Bohr-radius are desired for full understanding of spin phenomena in QWs.
