    • openAccess   A combined theoretical and experimental study of electronic structure and optical properties of β-ZnMoO4 microcrystals 

      Cavalcante, Laécio Santos; Moraes, E.; Almeida, M.A.P.; Dalmaschio, C.J.; Batista, N.C.; Varela, José A.; Longo, Elson; Siu Li, Maximo; Andres, Juan; Beltran, Armando Elsevier (2013)
      In this paper, a combined theoretical and experimental study on the electronic structure and photoluminescence (PL) properties of beta zinc molybdate ( -ZnMoO4) microcrystals synthesized by the hydrothermal method has ...

    • closedAccess   CIGSS films prepared by sol-gel route 

      De Oliveira, Larissa Helena; Todorov, Teodor Krassimirov; Chassaing, E.; Lincot, D.; Carda Castelló, Juan Bautista; Escribano López, Purificación Elsevier (2009)
      Homogeneous layers of amorphous oxides of Cu-In, Cu-In-Ga were deposited by a sol-gel method. Selenization, sulfurization and sequential selenization + sulfurization treatments were performed with elemental S and Se, ...

    • openAccess   Compression of scheelite-type SrMoO4 under quasi-hydrostatic conditions: Redefining the high-pressure structural sequence 

      Errandonea, Daniel; Gracia, Lourdes; Lacomba Perales, R.; Polian, A.; Chervin, J. C. American Institute of Physics (2013)
      The high-pressure behavior of tetragonal SrMoO4 was analyzed by Raman and optical-absorption measurements. Pressures up to 46.1 GPa were generated using diamond-anvil cells and Ne or N2 as quasi-hydrostatic pressure-transmitting ...

    • closedAccess   Cu2ZnSnS4 films deposited by a soft-chemistry method 

      Todorov, Teodor Krassimirov; Kita, M.; Carda Castelló, Juan Bautista; Escribano López, Purificación Elsevier (2009)
      Cu2ZnSnS4 films were deposited on glass substrates by the use of a printing technique. A series of different precursor materials was synthesized by a soft-chemistry route. Suspensions were prepared with or without the ...

    • openAccess   Structural and optical properties of ZnS/MgNb2O6 heterostructures 

      Santos, Luís P. S.; Cavalcante, Laécio Santos; Fabbro, Maria T.; Beltrán Mir, Héctor; Cordoncillo, Eloisa; Andres, Juan; Longo, Elson Elsevier (2015-03)
      In this letter, we report a simple and efficient synthetic procedure where the first step is a coprecipitation/calcination method used to obtain magnesium niobate MgNb2O6(MN) nanocrystals and in the second stage a microwave ...
