We have observed microsecond decay of bleaching and anomnalous induced absorp-tion in staggered alignment type-II Al..Ga. .As/AIAs ternary alloy multiple-quanturn-well structures. In a microsecond time scale, the time evolution of bleaching wasalmost the same as that of type-II photoluminescence. Tlce induced absorption,which occurs immediately after the photoexcitation, was obscrrved at the low-energytail of the exciton. These results indicate an interlayer F -X scattering process and suggest the resultant spatial redistribution of carriers:.
