Samples of Al 2 (B 4 O 7) 3:Cu were prepared by high-temperature solid-state ng electron microscopy showed a difference in the grain size for the copper doped and undoped aluminium borate with particulates of the undoped sample in the size 60–80 nm whereas . In order to confirm the relationship between the luminescence and the ratio of Ce3+/Ce4+ more clearly, a series of YAG:Ce3+ (Yttrium Aluminum Garnet, YAl5OCe3+) phosphors were pre- pared under different sintering atmosphere. A semi-quantitative analysis based on X-ray photoe-lectron spectroscopy (XPS) was introduced to study the mole ratio of Ce3+/Ce4+ in the as-synthesized . Full text.

      Yttria, Y 2 O 3, has great potential as a host material for solid-state lasers such as yttrium aluminum garnet-doped neodymium, Nd:YAG, and yttrium oxide doped with ytterbium, Yb:Y 2 O 3 [1, 2]. Other commonly known oxides, such as Al 2 O 3, MgO, and ZrO 2 ceramics, have attracted more interest than yttria [3, 4]. Therefore, the application of.

Abstract The room-temperature lattice spacings of some yttrium-samarium alloys have been determined by Debye-Scherrer, X-ray diffraction measurements.

In the composition range 090 Sm, the diffraction data indicate that the alloys have the structure, and extrapolation to Sm gives an axial ratio (c a) of for a hypothetical room temperature, form of samarium.

The present study is focussed on the investigation of electronic structure and implicitly local order changes around yttrium atoms in yttrium aluminosilicate glasses doped with iron.

Experimental Glass samples belonging to 17Y2O319Al2O3(x)SiO2xFe2O3 system (0 x 1 mol ) were obtained using oxides of reagent grade purity. The xray Kemission spectrum of yttrium in several compounds has been investigated using mm bentcrystal (mica) spectrograph.

Bhat, N. ] on FREE shipping on qualifying offers. CHEMICAL BONDING STUDIES OF YTTRIUM COMPOUNDS BY X-RAY K-EMISSION SPECTROSCOPYAuthor: N. Bhide, V. Bhat. Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group.

It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP) in a hexagonal or an orthorhombic, perovskite-like form, and the monoclinic Y 4 Al 2 O 9 (YAM). YAG, like garnet and sapphire, has no uses as a laser medium when r, after being doped with an.

Yttrium aluminium garnet, Y3AI5O12 - YAG, has a powder diffraction pattern that is easy to analyse in principle, but shows very interesting problems. These problems are re-vealed using an interactive graphics system, UNIRAS, intre-gated with some of the usual procedures for crystallo-graphic data processing.

For example, indexing with the. A cyclic furnace study was conducted between - C and - C to evaluate the effects of yttrium, chromium, and aluminum concentrations in nickel base alloy bond coatings and also the effect of the bond coating thickness on the performance of yttria-stabilized zirconia thermal barrier coatings.

We report photoluminescence and xraydiffraction studies on Smdoped yttrium aluminum garnet (YAG) to ultrahigh pressures of GPa in a diamondanvil cell at room temperature. Photoluminescence spectra from Sm:YAG could be clearly identified with increasing pressures to GPa.

The rapidly shifting fluorescence from diamond anvil obscures the Sm:YAG emission spectra.

Alloy characterization included x-ray diffraction (XRD), x-ray absorption (XAS), hydrogen absorption in a Sieverts apparatus.

Melt-grown crystals of yttrium aluminium garnet usually exhibit an optically imperfect central core region associated with the formation of facets on the solidliquid interface during growth. The nature of the optical inhomogeneity of the core region, and the general defect structure of the crystals, was investigated by the technique of X-ray diffraction topography.

These include solutions of the following: yttrium and aluminum nitrates in EtOH or nBuOH; yttrium 2-ethylhexanoate and alumatrane [N(CH2CH2O)3Al] in THF or EtOH; yttrium. Upon heating the precursors to °C, the formation of Y(OH)3 NTs was immediately observed, as evident by the diffraction peaks related to the hexagonal phase of Y(OH)3.

However, on the basis of X-ray absorption spectroscopic data, the local bonding and ordering began to resemble those of a stable Y(OH)3 crystal after a reaction time of 7 h.
