We have observed microsecond decay of bleaching and anomalous induced absorption in staggered alignment type-II Al x Ga 1- x As/AlAs ternary alloy multiple-quantum-well structures. In a microsecond time scale, the time evolution of bleaching was almost the same as that of type-II photoluminescence. The induced absorption, which occurs immediately after the photoexcitation, was observed at the low-energy tail of the exciton. These results indicate an interlayer Γ- X scattering process and suggest the resultant spatial redistribution of carriers.
