The photoluminescence spectra from a series of porous silicon samples formed in HF concentrations at constant current density and fixed forming times, are presented. A novel steplike behavior of photoluminescence peak energy was observed. A formation mechanism based on the quantum confinement of porous Si walls has been proposed to explain the experimental results.
