Abstract: Stable ultraviolet (UV) photoluminescence (PL) has been observed at room temperature in porous silicon (PSi) fabricated by photoetching in aqueous alkali fluoride solutions. The aqueous solutions used are 1 M NaF and 1 M KF.They give an alkaline reaction caused by partial hydrolysis. The PL peaks at ~3.3 eV have a full width at half maximum of ~0.1 eV, which is much smaller than those reported previously (?0.5 eV). Spectral analyses suggest that both quantum confinement and surface passivation effects enable the observation of UV emission in NaF- and KF-prepared PSi samples.
