We have succeeded to activate porous silicon layers by growing silicate phosphor particles in an oxidized porous silicon host. The method of impregnation is basically an immersion-heat treatment process. Efficient Blue, green and red luminescence has been observed from porous layers activated by Y2SiO5:Ce3+, Zn2SiO4:Mn2+ and Y2SiO5:Eu3+, respectively. The chromaticity coordinates of the prepared samples show that this choice of materials has a good coverage of colors, and can be used for display applications. This work introduces also the concept of "porous layers for display applications.".
