In this work, we report on an experimental investigation of the nonlinear optical properties near the first electronic resonance of thiol-capped CdTe quantum dots (QDs) being in the strong confinement regime. Using a cw laser excitation in a Z-scan experimental setup, we show the presence of saturat...
