The temperature dependence of photoluminescence (PL) in porous silicon has been investigated. It is found that the PL peak from the low porosity samples shows a red shift with decreasing temperature, but the blue shift of the PL peak is always observed in the high porosity samples. The temperature dependence of the PL peak shift observed experimentally can be qualitatively explained by the simulated curves of the luminescent efficiency versus wavelength.
