摘要
对多孔硅的研究意义、制备方法和发光机制进行了理论研究,提出了多孔硅的发光机制不能仅用某一种因素去解释,应该综合考虑各方面的影响。多孔硅发光是量子限制效应和表面态综合作用的结果。
The meaning、background and preparation of PS were introduced in the paper.Then the origin of this visible-light emission was disscused.Each model had its advantage in some specific cases,but meets difficulties in other cases.We suggest both the quantum confinement effect and the surface state mechanism should be considered in order to understanding photoluminescence of PS.
