Preparation of nanosized yttrium doped CeO2 catalyst used for photocatalytic application
(Elsevier, 2015)
In the present work, the pure CeO2 and yttrium doped CeO2 nanopowders were synthesized by the nitrate-fuel self-sustaining combustion method and calcined at 700 degrees C for 2 h. X-ray diffraction (XRD) and high resolution ...
Alkoxides-based sol-gel process - a smart way to obtain luminescent powders and films of yttrium garnets
(2012-03-01)
Undoped and rare-earth (RE=Ce, Tb or Eu) doped yttrium garnets have been synthesized in shape of powders and films by an original alkoxides-based sol-gel route. After a short review devoted to the elaboration of yttrium ...
Desenvolvimento da microestrutura do BaCeO3 dopado com ítrio sob a influência do ZnO como aditivo de sinterização: correlação com a condutividade protônica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2013-12-13)
Yttrium-doped barium cerate perovskites are promising electrolyte for solid oxide fuel cell (SOFC) due to high proton conductivity at intermediate temperature, 400-600°C. However, the proton conductivity is not an intrinsic ...
Thermo-optical characteristics and concentration quenching effects in Nd(3+)doped yttrium calcium borate glasses
(AMER INST PHYSICS, 2011)
In this work we present a comprehensive study of the spectroscopic and thermo-optical properties of a set of samples with composition xNd(2)O(3)-(5-x)Y(2)O(3-)40CaO-55B(2)O(3) (0 <= x <= 1.0 mol%). Their fluorescence quantum ...
Radioluminescence of rare-earth doped potassium yttrium fluorides crystals
(Pergamon-Elsevier Science Ltd, 2011-12)
The radioluminescence (RL) properties of K2YF5 crystals doped with Ce3+, Tb3+ and Dy3+ under ionizing irradiation excitation have been studied for the first time. The main objective of this work has been to assess the ...
Yttrium deposition on mesoporous TiO2: Textural design and UV decolourization of organic dyes
(2015)
This study discusses about the photochemical, topological and textural properties of yttrium-doped titanium dioxide (TiO2) photocatalysts. The mesoporous yttrium-doped TiO2 substrates prepared in this research work operate ...
