Abstract:
The determination of Y, Ce, Ba and Cu in a series of Y(1-x)Ce(x)Ba(2)Cu(3)O(y) samples has been performed using X-ray fluorescence fundamental parameter method. The composition is given in atomic percentage. The results agree well with those obtained by ICP. It is shown that this method is appropriate for the determination of compositions of the high temperature superconductors. In addition, the influence of oxygen on analytical elements has been discussed in this paper. The fraction of the matrix total mass absorption that is associated with oxygen for each analytical line can not be larger than 3.44%. The determined composition of the samples show different from their nominal composition,which may affect the properties of high temperature superconductor.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
