Anomalous oriented attachment growth behavior on SnO2 nanocrystals
Royal Society of Chemistry (2011)This work reports a detailed characterization of an anomalous oriented attachment behaviour for SnO2 nanocrystals. Our results evidenced an anisotropic growth for two identical 〈110〉 directions, which are equivalent according ... -
Characterization of amine stabilized CdSe/ZnS core–shell quantum dots by using triarylpyrylium dyes
Royal Society of Chemistry (2016-06-13)A new method to study the stabilizing primary amine ligands coordinated to the surface of CdSe/ZnS core–shell quantum dots has been developed. The method is based on the reactivity of fluorescent 2,4,6-triarylpyrylium dyes ... -
Enhanced Carrier Transport Distance in Colloidal PbS Quantum-Dot-Based Solar Cells Using ZnO Nanowires
American Chemical Society (2015-11)Nanostructured solar cells are a promising area of research for the production of low cost devices that may eventually be capable of complementing or even replacing present technologies in the field of solar power ... -
Microwave-hydrothermal synthesis of single-crystalline Co3O4 spinel nanocubes
The Royal Society of Chemistry (2013-07-29)An efficient microwave-hydrothermal (MAH) method has been developed for the synthesis of highly crystalline Co3O4 spinel nanocubes via beta-Co(OH)(2) without any surfactant assistance. The structure and surface chemical ... -
Piezoelectric Control of the Exciton Wave Function in Colloidal CdSe/CdS Nanocrystals
American Chemical Society (2016-05-25)Using multiband k·p calculations, we show that strain-engineered piezoelectricity is a powerful tool to modulate the electron−hole spatial separation in a wide class of wurtzite CdSe/CdS nanocrystals. The inherent ... -
Structural and Spectroscopy Study of a Novel Erbium Titanate Pink Pigment Prepared by Sol-gel Methodology
American Chemical Society (2008)Pyrochlore oxides show a large variety of physical and chemical properties depending on the ordering/disordering of the cations and oxygen vacancies. Taking account of these structural features and the luminescent properties ...
