Abstract
The properties of porous silicon Fabry–Perot microcavities impregnated with oxazine, a fluorescent dye, are investigated by photoluminescence and reflectance spectroscopy. The emission spectrum of the dye is noticeably modified by the cavity structures, being both the peak intensity increased and the linewidth narrowed, while the peak position coincides with that measured by UV–Vis reflectance. The results suggest that is possible, by simple methods, to prepare optically active hybrid materials integrating the properties of the inorganic host structure and of the organic guest.
