Ferraz Física, Astronomía y Matemáticas Nanoparticles Photoluminescence Electronic structure With a view to contribute to the understanding the surface effects on optical properties process, and its holein the electronic properties of the nanoparticles, CdS based nanoparticles are characterised by different experimentaltechniques and the experimental results compared to density functional theory calculations. Our resultsindicate that cubic CdS nanoparticles present a strong structural deformation, hexagonal reconstructed structurespreserve their lattice behaviour. Both cubic and hexagonal CdS nanoparticles are S-terminated after relaxation,even when mildly Cd-rich nanoparticles are considered. A broad peak observed in our PL measurements isinterpreted as an experimental evidence of the surface related peak observed around 1.8 eV in our calculatedDOS for the hexagonal relaxed structure. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436562 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.3B Vol.36 |
