Abstract

PbS quantum dots (QDs) with diameter of 2.9-7.4 nm were embedded into a porous matrix. The samples prepared by developed low-cost effortless method demonstrate linear dependencies of optical density and luminescence intensity on the QDs concentration and perfect homogeneity. Optical properties of quantum dots in the matrix were studied using absorption and steady-state and time-resolved photoluminescence spectroscopy. Luminescence lifetimes were found to be size-dependent and increase with decreasing of QDs size. The aging behavior of PbS QDs in a porous matrix was explored for a variety of QDs sizes. The energy transfer process in quasi-monodispersed PbS QDs ensemble was discovered.
