Abstract
The photoluminescence of porous silicon can be modified sensitively by surface adsorption of different kinds of molecules. A quite different effects of 9-cyanoanthracene and anthracene adsorption on the photolu minescence of porous silicon were observed. The adsorption of 9-cyanoa nthracene induced the photoluminescence enhancement, while anthracene adsorption resulted in photoluminescent quenching. An explanation of t he interaction of adsorbates with surface defect sites of porous silic on was suggested and discussed. (C) 1998 Elsevier Science S.A.
