Luminiscent properties of europium-1,4-benzenedicarboxylate synthesized at room temperature

Loera-Serna S., Medina-Díaz J.C., Carmona Téllez S., Universidad Autónoma Metropolitana, MX

For many years the lanthanides have been considered as a series of complex, difficult to understand elements, however, research on them has not been adequate. In view of the many properties that have, in the [...]

Structural and Luminescent properties of Europium benzene-1,3,5-tricarboxylate

Alejandre-Zuniga B.Y., Loera-Serna S., Medina-Velazquez D.Y., Universidad Autonoma Metropolitana-Azcapotzalco, MX

The increasing demand of optoelectronic devices requires the development of luminescent materials with high luminescence quantum efficiency and reduced energy consumption, to this organic matrix materials doped with rare earths offer an great alternative. The [...]

Color tunable nanophosphors

Sotiriou G.A., Schneider M., Pratsinis S.E., Particle Technology Laboratory, ETH Zürich, CH

In this study, yttrium oxide nanophosphors doped with Tb and Eu ions were made by flame aerosol technology. The emission color of these nanophosphors could be precisely tuned from green to red by tuning the [...]

Preparation of Y3Al5O12:Eu3+ waveguide films by sol-gel method

García Hernández M., García-Murillo A., de J. Carrillo Romo F., Torres Orozco C., García Hernández M., García-Murillo A., Ramírez-Meneses E., Cicata - IPN Unidad Altamira, MX

In this work, Y3Al5O12:Eu3+ (5 mol% Eu3+) optical thick films were obtained by sol-gel process. The films were dip-coated by dip-coating technique. The synthesis was accomplished using metal organic precursors, such as Al(tri-sec-butoxide) Al(OC4H9)3, yttrium [...]

Photoluminescence and Photoluminescence Excitation Measurements of Eu-Doped Nano-Si/SiO2 Thin Films

Nery G.A., Fonseca L.F., Liu H., Resto O., Weisz S.Z., University of Puerto Rico at Rio Piedras, PR

Europium (Eu) ions are already used in significant visual technological applications. We attempted to determine if a silicon nanoparticle (nano-Si) / Europium interaction could occur. The energy transfer from nano-Si to rare earth ions has [...]
