The non-linear optical properties of CdSe microcrystallites exhibiting three-dimensional quantum confinement effects are investigated using (i) nanosecond pump-probe spectroscopic techniques and (ii) single beam saturation experiments to study the dependence on particle size. The experimental data show unique non-linear behaviour arising from state filling and Coulomb effects as well as trap-related phenomena exceedingly different from other non-linear optical materials.
