Diffusion of implanted europium in glassy carbon [PDF]

, 2019
Thesis (PhD)--University of Pretoria, 2019.In my PhD study glassy carbon samples were implanted with 250 keV europium ions at room temperature and at 100 oC. The main purpose of my study was to study the diffusion properties of the europium in the glassy

Enhancement of europium luminescence in tetracycline–europium complexes in the presence of urea hydrogen peroxide

, 2005
5 p. : il.An increase in the europium emission band was observed, for the first time, with addition of urea hydrogen peroxide to the tetracycline–europium (Tc–Eu)solution.

Potential of Y₂Sn₂O₇:Eu³⁺, Dy³⁺ Inorganic Nanophosphors in Latent Fingermark Detection

Crystals
In this work, we investigated the potential of Eu3+/Dy3+-codoped Y2Sn2O7 fluorescent nanophosphors to visualize latent fingermarks. We prepared these nanophosphors with various doping concentrations by the conventional coprecipitation reaction.

Effect of the Addition of WO₃ on the Structure and Luminescent Properties of ZnO-B₂O₃:Eu³⁺ Glass

Molecules
Glasses with the compositions in mol % of 50ZnO:(50 − x)B2O3:0.5Eu2O3:xWO3, x = 0, 1, 3, 5 and 10 were obtained by applying the melt-quenching method and investigated by Raman spectroscopy, DSC analysis and photoluminescence (PL) spectroscopy.

Conversion Propane in the Presence of Europium Vanadite and Europium Vanadate

, 2020
Features of propane conversion in the presence of Europium vanadite and Europium vanadate, both produced via solid-phase synthesis, are studied. It is shown that EuVO3 catalyzes mainly the propane cracking process to form methane and ethylene, while EuVO4 equally accelerates both cracking and the dehydrogenation of propane.
