“…The FTIR spectroscopy was performed at RT on PS/Co before and after annealing process and compared to that obtained on PS (figure1). 2 [5,[7][8][9], therefore the band at -1 cm 470 2 can be attributed to (cobalt-oxygen)-silicon bonding. We also observe a band at affect the Si-Si and Si-H 2 vibrations.…”

We report Raman and photoluminescence studies of cobalt-porous silicon nanocomposites (PS/Co). Cobalt was introduced in porous silicon (PS) by immersion method using CoCl 2 aqueous solution. The presence of cobalt in PS matrix was identified by FTIR spectroscopy and EDX analyses. The Raman spectroscopy revealed the presence of Si bonded to cobalt oxide in PS/Co. We discuss also the Raman spectra of PS and PS/Co samples under different annealing temperatures ranging from room temperature (RT) to C 600°. The optical properties

Within this work the utilization of nanostructured silicon as host material for filling with various magnetic nanostructures is reviewed whereas the magnetic and optical properties of the gained composite systems are elucidated. The metal filling of the pores is mainly performed by electroless deposition or by electrodeposition which is discussed by means of some examples. Furthermore, two different types of porous silicon (PSi) morphology are used for the deposition procedure. On the one hand microporous silicon offering luminescence in the visible range is utilized as template material. It offers a branched morphology with a structure size between 2 and 5 nm. In this case not only the magnetic response is investigated but also the influence of the metal filling on the optical properties. On the other hand mesoporous and macroporous silicon in it's low pore regime is employed which offers straight pores with diameters up to 90 nm. In this case the magnetic response strongly depends on the size, the geometry and the spatial distribution of the metal deposits within the pores. A crucial role plays also the morphology of the porous silicon, especially the distance between adjacent pores which is an important parameter regarding magnetic interactions.

“…low concentration reinforcing material required to reinforce throughout the matrix, higher interfacial surface area for interaction with matrix phase, high aspect ratio of the nanomaterials for the improvement of microstructure of the nanocomposite, less stress concentration in case of homogeneous dispersion and distribution of nanomaterial in the matrix phase. Properties of nanocomposite materials depend on the type of matrix, nano reinforcements and their proportion, dispersion and distribution of nano reinforcements in the matrix material, and interfacial interaction between metal matrix and nano reinforcement materials, and manufacturing routes [8,[10][11][12][13][14][15].…”
