Influence of Trap States on the Kinetics of luminescence and Induced Light Absorption by Si Nanoparticles in a SiO2 matrix at their Excitation with Femtosecond Laser Pulses
Keywords:trap states, transient absorption, lux-intensive characteristics, fluence, effect of luminescence fatigue, CCD-camera, Auger-process, pump-probe, white supercontinuum, telegraph-like signal
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.
