Photochemical deposition, characterization and optical properties of thin films of ThO2
(Elsevier Ltd, 2019)
Thorium oxide thin films were successfully prepared by direct UV irradiation of amorphous films composed of thorium(IV) β-diketonate precursor complexes on Si(100) and quartz substrates. The ThO2 films were characterized ...
Uranium isotopes as radioactive pollutants in groundwaters of the Morro do Ferro thorium deposit, Brazil
(1991-01-01)
Groundwater and surface water samples were collected at Morro do Ferro, a thorium and rare earth deposit located on the Pocos de Caldas Plateau, Minas Gerais State, Brazil, to evaluate if the mechanisms related to the ...
Effect of annealing temperature on the structural, morphological and optical properties of ThO2 thin films grown by photochemical metal–organic deposition
(Elsevier Ltd, 2019)
© 2019In this work, we report the influence of annealing temperature on the structural, morphological and optical properties of ThO2 thin films deposited on fused quartz and (100) silicon substrates by photochemical ...
Behavior of thorium plutonium fuel on light water reactors
