Photoluminescence (PL) spectral change in porous silicon (PS) was investigated during post-anodization in 0.1 kmol/m3 KCl and 0.1 kmol/m3 HClO4 aqueous solutions. The PL intensities of the PS immersed in both solutions were enhanced with an increase of the current density of anodization. The PL enha...
