并使激子吸收峰从红外波段进入可见光波段。

And it makes the absorption peak of the exciton move to higher energy.

观察到轻、重空穴对应的激子吸收峰（LH和HH）及台阶状态密度。

The exciton absorption resonaces (HH and LH) and step accumu-tive density Of state have been observed.

在较低磁场下，其引入的限制势对激子吸收谱的主要特性的影响可以忽略。

At low magnetic field, the effects of magnetic-field-induced confining potential on the main features of the excitonic spectra are negligible.
