CuxS nanocrystals (NC's) with average radius of approx.4 nm are grown in the glass matrix originally containing CdS NC's. The prepared nanostructures clearly exhibit the effect of a 3D carrier confinement which is manifested as well as resolved peaks in linear absorption. The structure of the absorption spectra shows the presence of the NC's formed by different CuxS phases. The enhanced nonlinearity results from the increased values of the carrier lifetime and the linear absorption.
