We report the observation of strong luminescence from porous Si grains containing Si nanocrystallites embedded in polymethyl methacrylate disks. In concentrated samples, forward and backscattered photoluminescence spectra were just as strong as in porous Si on Si wafers. This new result indicates that porous Si grains could be embedded in nonconducting polymers and would retain all its inherent characteristics as in porous Si layers on Si wafers.
