Y2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing YO6 octahedra.

2016年3月1日 · The microstructural characterization of resultant powder was carried out by means of XRD. A detailed investigation was conducted on the XRD peak broadening of Y 2 O 3 using Williamson-Hall method by assuming three models namely uniform deformation model, uniform stress deformation model, and uniform energy density deformation model.

There is a strong correlation between the x-ray diffraction (XRD) peak intensity and the thermoluminescent glow curve intensity. The glow curve displays at least two peaks at 140 °C and 230 °C.

We successfully fabricated Y2O3:RE3+ (RE = Eu, Tb, and Dy) core and core–shell nanophosphors by the molten salt method and sol–gel processes with Y2O3 core size of the order of 100~150 nm. The...

2021年2月15日 · The crystallographic phase of the Y 2 O 3:Yb 3+ /Er 3+ UCNPs was confirmed by powder X-ray diffraction (XRD) patterns using an X-ray diffractometer with Cu K radiation at 40 kV and 200 mA (TTR III system, Rigaku). The size and morphology of these UCNPs were obtained by transmission electron microscopy (TEM) (Tecnai G2 F20, FEI).

In this paper, Eu doped Y2O3 nanophosphors are prepared at temperature 600oC by the combustion method. X-ray diffraction patterns confirm the formation of pure cubic phase of Y2O3.
