Figure 2From: Radiative and nonradiative relaxation phenomena in hydrogen- and oxygen-terminated porous siliconPL decay curves. The PL decay curves of H-PSi measured at a photon energy of 2.03 eV (610 nm) and at various temperatures. The solid lines present the best fit to a stretched exponential function (Equation 1). Inset shows the PL spectrum of H-PSi measured at room temperature.Back to article page
