The controlled synthesis of PbSe quantum dots in Se-doped glass matrix (SiO2-Na2CO3-Al2O3-PbO2-B2O3) with narrow size distributions was achieved. Quantum dot size can be manipulated by tuning annealing time in the process of thermal treatment. The PbSe QD sizes estimated by 4 x 4 k (.) p theory were in very good agreement with the measurements of atomic force microscopy. (c) 2006 Elsevier B.V. All rights reserved.
