Abstract

We first recall the results of our extensive studies of the nonlinear properties of commercially available semiconductor-doped glasses which led us to a fairly complete understanding of the nonlinearity in these materials. We also observed experimentally that at high fluences, Auger recombination of free carriers is an efficient recombination process in these small crystallites. We then present recent results obtained on experimental semiconductor-doped glasses clearly exhibiting the quantum confinement effect. We observed that phonon broadening is very important in these very small Cd S Se particles. At low temperature however, spectral hole burning was observed. These results are in agreement with conventional models of electron-phonon coupling.
