2019年10月1日 · The high-temperature phase transformation process of Tb 2 O 3 in an oxygen-free atmosphere was further investigated by in-situ X-ray diffraction (XRD), DSC-TG and thermomechanical analysis (TMA).

Tb2O3 nanotubes were fabricated by calcination of the precursor Tb (OH)3 nanotubes prepared by a template-assisted hydrothermal route. The oxide nanotubes have outer diameters ranging from 80 to...

The structure of as-synthesized samples was characterized by using several techniques, including X-ray diffraction (XRD) spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy (XPS...

2020年5月26日 · We report a joint experimental and theoretical investigation of the high-pressure structural and vibrational properties of terbium sesquioxide (Tb2O3). Powder x-ray diffraction and Raman scattering measurements show that cubic (C-type) Tb2O3 undergoes two phase transitions up to 25 GPa.

2020年7月7日 · In this work, we present a thorough experimental and theoretical study on the structural and vibrational properties of Tb 2 O 3 under compression, where powder X-ray diffraction (XRD) and Raman scattering (RS) measurements at HP have been complemented with theoretical ab initio calculations.

Specifically, Tb3+-doped metastable CaAl2Si2O8 showing green phosphorescence was prepared via a solid-state reaction between expanded kaolinite, a methoxy-modified kaolinite, having Tb3+ ions...
