Chemical vapor deposition coupled with a powder-flowing apparatus was used to prepare composite polycrystalline diamond layers containing light-emitting Si nanoparticles. The room-temperature photoluminescence behavior of the material in the 1.6-2.5 eV energy range is characterized by a strong increase of the emission efficiency from the Si nanostructures embedded in the diamond matrix. Results show that it is possible to tune the luminescence frequency in the yellow-green spectral region by selecting the size of the inserted Si grains.
