Diener, J. and Ben-Chorin, M. and Kovalev, D. and Ganichev, Sergey and Koch, F. (1996) Excitation of the porous silicon photoluminescence by a multiphoton vibronic process. Thin Solid Films 276 (1-2), pp. 116-119.
We study the emission of photons from porous Si after high-level vibrational excitation in the Si---O absorption band using a pulsed CO2 laser. Narrow resonances in the efficiency of light generation are discovered at 1030 cm−1 and 1084 cm−1. For excitation at 1030 cm−1 the familiar photoluminescence band of porous Si appears. Time-resolved pump-to-probe experiments show the same decay times for ...
