Effect of the synthesis conditions on the properties of Co embedded porous Si nanostructures
The electrodeposition of cobalt in the porous silicon (PSi) substrate was investigated in
terms of the deposition times and current densities. The PSi/Co samples were characterized
by SEM, XRD, Raman, and photoluminescence (PL) spectroscopies. The results indicated
that for all current densities, the PL intensities of PSi/Co samples with shorter deposition
times (ts≤ 20 min) increased due to spherical Co nanoparticles (NPs) could be created the
new recombination centers, compared to that of the undeposited PSi. On the other hand, the …
