We have studied the optical properties of Al.Ga. .As-AIAs ternary alloy multi-quantum-well structures around two F -X crossovers by means of photolumines-cence and absorption saturation. In the photoluminescence, the peak due to the n = lheavy exciton (T -T) is observed for Al composition x from 0 up to 0.34. When x is0.34 or more, another kind of the peak due to the T -X recombination (recombina-tion between an ,X'-electron in AIAs and a f-hole in Al.Ga. .As) is observed in thelow energy side, corresponding to the first F -X crossover. In the absorption satura-tion experiments, on the other hand, the saturation was observed in all the samples ex-cept the A1..,.Ga...,As-AIAs sample corresponding to the second T -X crossover.The fact suggests that f-electrons relax to the X-state is the Al.Ga. .As alloy veryquickly compared with the other relaxation processes such as the T -frecombinationin Al.Ga. .As and the transfer of a f-electron in Al.Ga. .As to ,X'-state in AIAs.
