    • openAccess   Acetone gas sensor based on α-Ag2WO4 nanorods obtained via a microwaveassisted hydrothermal route 

      Da Silva, Luis F.; Catto, Ariadne C.; Avansi, Waldir; Cavalcante, Laécio Santos; Mastelaro, Valmor Roberto; Andres, Juan; Aguir, Khalifa; Longo, Elson Elsevier (2016)
      This manuscript addresses the synthesis of one-dimensional (1D) α-Ag2WO4 nanorod-like structures via a microwave-assisted hydrothermal method to be used as an acetone gas sensor. The nanorods showed excellent gas-sensing ...

    • openAccess   Correlation in narrow nanorods: a variational potential–configuration interaction scheme 

      Planelles, Josep; Climente, Juan I.; Royo Valls, Miguel; Movilla, Jose L. Institute of Physics (2009)
      Abstract. Full configuration interaction calculations of two electrons in narrow semiconductor nanorods are carried out employing different orbital basis sets. It is shown that the usual configurations built from ...

    • openAccess   Dielectric confinement of excitons in type-I and type-II semiconductor nanorods 

      Royo Valls, Miguel; Climente, Juan I.; Movilla, Jose L.; Planelles, Josep Institute of Physics (2011-01-12)
      We theoretically study the effect of the dielectric environment on the exciton ground state of CdSe and CdTe/CdSe/CdTe nanorods. We show that insulating environments enhance the exciton recombination rate and blueshift the ...

    • openAccess   From quantum dots to quantum wires: electronic structure of semiconductor nanorods 

      Planelles, Josep; Royo Valls, Miguel; Ballester Caudet, Ana; Pi, Martí American Physical Society (2009)
      The transition bridge between zero-dimensional quantum dots and one-dimensional quantum wires is explored theoretically by means of the construction of the addition energy spectra of nanorods with different lengths. Spin ...

    • openAccess   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 ...

    • openAccess   Photolumiscent properties of nanorods and nanoplates Y2O3:Eu3+ 

      De Moura, Ana Paula; De Oliveira, Larissa Helena; Paris, Elaine Cristina; Siu Li, Maximo; Andres, Juan; Arana Varela, José; Longo, Elson; Rosa, Ieda Springer Verlag (2011)
      Nanorods and nanoplates of Y2O3:Eu3+ powders were synthesized through the thermal decomposition of the Y(OH)3 precursors using a microwave-hydrothermal method in a very short reaction time. These powders were analyzed by ...

    • closedAccess   Sb2S3-Sensitized Photoelectrochemical Cells: Open Circuit Voltage Enhancement through the Introduction of Poly-3-hexylthiophene Interlayer 

      Heo, Jin Hyuck; Im, Sang Hyuk; Kim, Hi-jung; Boix, Pablo P; Lee, Suk Joong; Seok, Sang Il; Mora-Sero, Ivan; Bisquert, Juan American Chemical Society (2012)
      The Sb2S3-sensitized photoelectrochemical cells (Sb2S3–SPECs) in cobalt electrolyte were fabricated by depositing Sb2S3 on the macroporous TiO2 nanorods electrodes and consecutively spin-coating P3HT (Poly-3-hexylthiophene) ...

    • openAccess   Strong configuration mixing due to dielectric confinement in semiconductor nanorods 

      Climente, Juan I.; Royo Valls, Miguel; Movilla, Jose L.; Planelles, Josep American Physical Society (2009)
      The interaction between electron-electron and electron-hole pairs in semiconductor nanorods embedded in dielectric media is investigated using a configuration-interaction method. Contrary to spherical quantum dots of similar ...
