Dantas Física, Astronomía y Matemáticas Oxide glass PbS quantum dots Synthesis and characterization The fusion method was used to produce PbS quantum dots (QDs) embedded in S-doped glass matrix (SiO2-Na2CO3-Al2O3-PbO2-B2O3:S). Measurements of optical absorption (OA), photoluminescence (PL) and atomicforce microscopy (AFM) have been carried out in order to characterize the produced QDs. A strong red-shiftobserved in the optical features with an increase of the annealing time indicates an increase in QD-size. The QDsizes predicted by k.p theoretical results were confirmed by AFM observation. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436343 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2A Vol.36 |
