Diener, J. and Ben-Chorin, M. and Kovalev, D. and Ganichev, Sergey and Koch, F. (1995) Light from Porous Silicon by Multiphoton Vibronic Excitation. Physical Review B 52 (12), R8617-R8620.
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 and 1084 cm-1. Time-resolved experiments on the luminescence and the ir-induced changes in optical transparency show that the two excitation modes are characterized by different ...
