U and Th thin film neutron dosimetry for fission-track dating: Application to the age standard Moldavite
(2005-12-01)
Neutron dosimetry based on U and Th thin films was used for fission-track dating of the age standard Moldavite, the central European tektite, from the Middle Miocene deposit of Jankov (southern Bohemia, Czech Republic). ...
Potentialities and practical limitations of absolute neutron dosimetry using thin films of uranium and thorium applied to the fission track dating
(Elsevier B.V., 1999-06-01)
Neutron dosimetry using natural uranium and thorium thin films makes possible that mineral dating by the fission-track method can be accomplished, even when poor thermalized neutron facilities are employed. In this case, ...
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 ...
Durango apatite fission-track dating using length-based age corrections and neutron fluence measurements by natural thorium thin films and natural U-doped glasses calibrated through natural uranium thin films
(Elsevier B.V., 2002-08-01)
In this work, we present an approach for neutron fluence measurements based on natural thorium thin films and natural uranium-doped glasses calibrated through natural uranium thin films to be used for dating with the ...

Thickness dependence of structure and piezoelectric properties at nanoscale of polycrystalline PZT thin films
(2012-10-31)
Lead zirconate titanate Pb(Zr 0.50Ti 0.50)O 3 (PZT) thin films were deposited by a polymeric chemical method on Pt(111)/Ti/SiO2/Si substrates to understand the mechanisms of phase transformations and the effect of film ...

The Th/U ratio in minerals by a fission-track technique: Application to some reference samples in order to estimate the influence of Th in fission-track dating
(2002-01-01)
In this work, a recent technique for the determination of the Th/U ratio in minerals and glasses was applied to relevant samples used as reference in fission-track (FT) dating. This technique, developed for estimating the ...
