Abstract

Experiments for determining the nonlinear optical properties of thiol-capped CdTe QDs [1] in strong confinement regime were performed on a set of samples with diameters in the range of 1. 7 - 2. 3 nm and with the linear absorption and emission properties presented in figure 1. The samples are specially designed to have a PL peak in green, where the laser used in our experiments (SHG Nd: YAG, c. w., λ =533nm) provides the excitation.
