摘要：
PbS nanoparticles with features of quantum dots (QDs) have been fabricated in boron-silicate glass matrix. Their mean diameter was found to be in the range of 3.4-8.2 nm from the optical spectroscopy data due to their explicit quantum confinement effect. The particle size and position of the absorption bands can be controlled through the regimes of thermal treatment of the glasses. SAXS technique showed near to monodisperse size-distribution of QDs and possible ordering within the glass matrix.
