La(OH)3:Eu3+and La2O3:Eu3+nanorod bundles: growth mechanism and luminescence properties

Luminescence Properties of TeO2-LiF-Gd2O3 Glasses

In this work, the structural properties and spectroscopic behavior 80 mol.%TeO2-20mol.%LiF glasses which were doped with 0. 05, 0. 2 mole% Gd2O3 have been studied. It was shown that,  by increasing the amount of Gd2O3 the glass stability was decreased. The PL emissions at 431nm and 627nm wavelengths were distinguished by 320nm excitation. The FT-IR analysis showed deformed TeO4 groups in these ...

Structure, Luminescence, and Transport Properties of EuVO4

Metastable scheelite EuVO4 was stabilized by a high temperature and pressure method, which was transformed into a stable zircon phase by annealing treatment in air. Scheelite EuVO4 gave strong emissions with a dominant peak at 617 nm associated with the D0F2 transition of Eu . Eu Mössbauer spectra indicated that the isomer shift for the metastable scheelite phase was ca. 0.5 mm/s lower than tha...

Scatter factor and hepatocyte growth factor: activities, properties, and mechanism.

Scatter factor (SF) was first identified as a fibroblast-derived protein which disperses (i.e., "scatters") cohesive colonies of epithelium. SF-like proteins were found in human smooth muscle cell conditioned medium, amniotic fluid, and placental tissue. SFs markedly stimulate migration of epithelial, carcinoma, and vascular endothelial cell types at picomolar concentrations. Hepatocyte growth ...

Growth and luminescence properties of micro- and nanotubes in sintered tin oxide

Effect of LiCl on the Microstructure and Luminescence Properties of YVO4:Eu3+ and YBO3:Eu3+ Phosphors

In this investigation, Eu3+ doped YVO4 /YBO3 phosphors were synthesized individually by conventional solid state method at 1100 °C under atmosphere condition. Meanwhile, different amounts of LiClwere used as the flux compound to modify the morphology of the phosphor particles and also final luminescence properties. It was concluded that even small amounts of fluxes play a vital role in the grow...
