Description
| - We report on ultrafast photoluminescence (PL) spectroscopy of blue and red-emitting silicon nanostrucures. We prepared samples of porous Si with different dominating PL bands in time-integrated PL spectrum. These samples show also striking differences in ultrafast PL dynamics. For the red-emitting samples we observe rapid PL onset followed by a two-exponential decay, which is spectrally dependent. For the blue-emitting porous Si the PL builds up several ps and decays mono-exponentially with spectrally independent PL rise and decay times. Our results indicate that a dominant part of the blue and red emission comes from two distinct species with different energy states structures. This is also supported by two-photon absorption induced PL measurements. The two-photon and one-photon absorption induced PL spectra, which are identical for the red-emitting samples, differ substantially for the blue-emitting ones.
