Abstract

Experiments for determining the nonlinear optical properties of thiol-capped CdTe QDs 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 are presented. The samples are specially designed to have a PL peak in green, where the laser used in our experiments (SHG Nd:YAG, c.w., lambda=533nm) provides the excitation.
