N2 - We have investigated the temperature dependence of the visible luminescence of porous silicon and other Si-based luminescent materials (as-prepared and annealed siloxene, amorphous Si:O:H alloys) at temperatures between 10 and 359 K. In all samples, the decrease of the luminescence intensity, I(T), at temperatures > 100 K can be described by the relation I0/I(T) = 1 + exp(T/T0). At temperatures < 100 K, some of the strongly luminescent samples show a decrease of the luminescence intensity with decreasing temperature. We have found this decrease to be related to a "fine structure" in the luminescence spectra of yet unknown origin.
