LOPEZ, I. A.; VAZQUEZ, A.  e  GOMEZ, I.. Microwave assisted synthesis of CdS nanoparticles and their size evolution. Rev. mex. fis. [online]. 2013, vol.59, n.2, pp.160-164. ISSN 0035-001X.

The study of the size evolution of CdS nanoparticles in aqueous dispersion is presented in this paper. The sodium citrate was employed as stabilizer of CdS nanoparticles synthesized by microwave assisted synthesis. Analysis of this study was carried out by UV-Vis spectrophotometry, by comparison of the band gap energy using theoretical and empirical models. Results obtained show that the synthesis conditions produce CdS nanoparticles with diameters below of 6 nm, which remains stabilized by at least 14 days. These characteristics were confirmed by transmission electron microscopy. The X-ray diffraction pattern confirms cubic phase of the CdS nanoparticles.
