Figure 4From: Radiative and nonradiative relaxation phenomena in hydrogen- and oxygen-terminated porous siliconTriplet and singlet lifetimes and energy splitting. (a) the upper singlet lifetime; (b) the excitonic energy splitting; (c) the lower triplet lifetime (extracted from the fit to the singlet-triplet model; see FigureĀ 3) as a function of the photon energy.Back to article page
