The evidence of successful growth of Mn-doped PbS (Pb1-xMnxS) nanocrystals (NCs) in SiO2-Na2CO3-Al2O3-PbO2-B2O3 template; using the fusion method; is reported on in this study. The as-grown Pb1-xMnxS NC is characterized using optical absorption; electron paramagnetic resonance; and atomic force microscopy. The data are discussed in terms of two distinct scenarios; namely a core-doped and a shell-doped nanostructure. © 2008 Elsevier B.V. All rights reserved;
