Details of powder diffraction data measured at 11-BM for standard reference materials are listed below and are available in several formats. These are periodically updated. Contact 11-BM staff with questions. Data are typically measured at ~ 30 keV under ambient conditions. Check the file header for full details and scan parameters.

PXRD patterns of the NIST SRM660b LaB6 line-profile standard in a 0.5 mm capillary collected with the multipurpose diffractometer at a sample-to-detector distance of 50 cm, (a) with the Ge...

We explain how doping LaB6 nanoparticles with lanthanide metals (Y, Sm, and Eu) red-shifts the absorbance band and describe research focusing on the correlation between size dependent and...

2020年8月21日 · PXRD pattern of line profile standard SRM660c (LaB 6), a = 4.156826(8) Å, collected with a benchtop powder diffractometer (Bruker D2 Phaser), using Ni-filtered CuKα radiation produced at 30 kV, 10 mA, and a LynxEye strip detector.

This Standard Reference Material (SRM) is intended for use as a standard for calibration of diffraction line positions and line shapes determined through powder diffractometry. A unit of SRM 660a consists of approximately 6 g of lanthanum hexaboride powder bottled under argon.

High-quality, uniform, one-dimensional (1D) lanthanum hexaboride (LaB6) nanostructures with different morphologies (for example, sparse or dense nanoneedles, or nanorods and nanowire arrays) were...

2010年8月1日 · It consists of approximately 6 g LaB6 powder prepared using 11B isotopically enriched precursor material so as to render the SRM relevant to the neutron diffraction community.

2019年7月23日 · Powder X-ray diffraction (XRD) is a common characterization technique for nanoscale materials. Analysis of a sample by powder XRD provides important information that is complementary to various microscopic and spectroscopic methods, such as phase identification, sample purity, crystallite size, and, in some cases, morphology.

• Standards: – Si, LaB6, Ni, ZnO, TiO2, CeO2, Al2O3, Cr2O3, and Y2O3. • Samples can be used as calibrants: – X-ray and neutron powder diffraction 11 • The National Institute of Standards and Technology (NIST) supplies standard calibrating materials for many applications.

Using LaB6 as an instrumental broadening standard with a Cauchy FWHM of 0.133o, the cor rected FWHM is 0.167o, and the Scherrer equation gives a crystallite size of 512 Å. The spotty diffraction ring is due to the large crystallites compared to the sampling volume (beam size).
