In situ growth of Ag nanoparticles on alpha-Ag2WO4 under electron irradiation: probing the physical principles
San-Miguel, Miguel A.; da Silva, Edison; Zanetti, Sonia M.; Cilense, Mário; Fabbro, Maria T.; Gracia, Lourdes; Andres, Juan; Longo, Elson IOP Publishing Ltd (2016-04)Exploiting the plasmonic behavior of Ag nanoparticles grown on α-Ag2WO4 is a widely employed strategy to produce efficient photocatalysts, ozone sensors, and bactericides. However, a description of the atomic and electronic ... -
Microwave-hydrothermal synthesis of single-crystalline Co3O4 spinel nanocubes
Mulinari, Tatiana A.; La Porta, Felipe A.; Andres, Juan; Cilense, Mário; Varela, José A.; Longo, Elson 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 ... -
Photoluminescence in quasi-amorphous Pb0.8X0.2Zr0.53Ti0.47O3 (X = Ca, Sr and Ba) powders: An optical and structural study
Longo, V. M.; Silva, M. S.; De Figueiredo, A. T.; Franco, R. W. A.; Vila, Carles; Cilense, Mário; Varela, José A.; Longo, Elson; Andres, Juan Elsevier (2009)Crystalline and quasi-amorphous PZT and PZT:X (X = Ca, Sr and Ba) powders were obtained by the polymeric precursor method. Electron paramagnetic resonance (EPR) and photoluminescence (PL) data suggest that the presence of ...
