Abstract

Cu_xS 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 Cu_xS phases. The enhanced nonlinearity results from the increased values of the carrier lifetime and the linear absorption.
