摘要：
Porous silicon prepared by pulse electro etching is heat treated in O 2 atmosphere with an enhancement of its PL peak and an improvement of its PL stability. The PL peak of a sample porous silicon treated in O 2 atmosphere at 1 000 ℃ presents itself a three-peak structure and, compared with an un- heat-treated sample, there exists blue shift of ～ 40 nm.
