Examines the visible and near-infrared (IR) photoluminescence (PL) emission spectra from p-type porous silicon(111) microstructures. Observation of strong near-infrared intrinsic band-to-band emission above and below the bulk silicon band gap; Enhancement of the luminescence in the IR spectra; Increase in PL intensity with the excitation energy.
