There is currently experimental interest in assemblies of Gd2O3 clusters. This has motivated the present study in which a single such cluster in free space is examined quantitatively by spin-density functional theory, with appropriate relativistic corrections incorporated for Gd. First, the nuclear geometry of the cluster is optimized, and it is found to be such that the two Gd atoms lie in a s...

2014 Fast electron energy loss spectroscopy (FEELS) is used to obtain the various optical constants over a large energy range in Sc, Sc2O3, Y, Y2O3, Gd, Gd2O3, Dy, LaF3, GdF3, DyF3, Th, ThF4, U and UF4. For the first time a comprehensive study of the 3p to 6p spectra is performed in the 30-60 eV range, Z varying between 21 and 92. Interesting common features of these resonant p spectra are emph...

Abstract Gadolinium oxide nanorod (Gd 2 O 3 NR) was fabricated on an n-type silicon substrate by catalyst-free glancing angle deposition (GLAD) technique. The as-grown sample annealed at 500 °C to investigate the impact of annealing structure and optical properties. XRD analysis reveals improvement in crystal after annealing. Field emission scanning electron microscope (FE-SEM) energy dispersiv...

Rare earth oxides such as La2O3 and Gd2O3 are abundant in waste optical glass. The separation of rare is beneficial to the recycling resources. In this study, oxide particles were separated from using high gradient magnetic separation, influence different fluid media (i.e., water, anhydrous ethanol, their mixture) on results was investigated. By measured zeta potential water/ethanol pH water wi...

The electrical conductivity of LiCl-GdCl3 molten systems with the gadolinium chloride additions ranging from 0 to 23 mol% was measured depending on both temperature and concentration GdCl3. molar GdCl3-LiCl system is calculated taking into account assumption additivity volume mixture. obtained dependencies can be approximated by Arrhenius-type equation. effective activation energy Ea increased ...

Rare earth-doped materials are successfully utilized as non-contact optical temperature sensors. Thermal sensing is usually based on the ratiometric technique between two separate emission lines originated from thermally-coupled levels. We study Gd2O3:Eu3+ 1 at.% and YAG: Eu3+ 4 phosphors luminescence thermometers in 298–473 K range using both conventional experimental Judd-Ofelt theoretical ap...
