Luminescence Study of Flouorescent Dye Impregnated into Si-based Nanoporous Alumina

Abstract

Abstract: Si-based nanoporous alumina can be used as the host matrices for a variety of luminescent media to obtain light dots in nanometer size.In this experiment three kinds of fluorescent dyes are impregnated into Si-based nanoporous alumina and utilized to obtain blue, green and red emission at room temperature.The blue-shift of emission spectra is found and the interaction mechanism between the fluorescent dye and the host matrices such as nanoporous alumina and porous silicon is discussed.The results show that the PLproperties of fluorescent dye are directly affected by the PLmechanism of the host matrices.

Key words: Fluorescent dye, Photoluminescence, Porous alumina, Porous silicon
