In this study, enhancement and stabilization of photoluminescence (PL) by porous silicon (PS) were investigated. The PS samples were metallized in solutions containing 3 mM NaNO3 metal salt using immersing plating method. The surface bond configuration of PS was monitored by Fourier Transmission Infrared Spectroscopy (FTIR) and it was found that the PS surface was oxidized after the metallization. The PL intensity increased after certain critical immersion times and PL spectrum shifted towards the high energy regi...
