Abstract

We report on the results of our researches dealing with nonlinearities caused by trap states in the lux-intensity characteristics of the intrinsic emission band of Si nanoparticles embedded into a SiO2 matrix and the dependence of the temporal characteristics of induced absorption on the pump femtosecond pulse fluence.
