高壓下物質的非彈性X光散射

Inelastic X-Ray Scattering Study of Material under High Pressure

摘要


本文提供有關利用鑽石鉆進行高壓實驗技術的簡介,同時應用並結合同步輻射光源之X光非彈性散射(IXS)光譜,研究在高壓作用下物質的物理性質。我們藉由X光非彈性散射光譜技術,完成了高解析(lifetime-broadening suppressed)X光吸收光譜(XAS)和X光放射光譜(XES)的量測,研究在壓力的誘導下物質中自旋態與價態的轉變。

This report introduces the high pressure experimental techniques using diamond anvil cell. By using synchrotron radiation light source with inelastic X-ray scattering spectroscopy, the physical properties of materials under high pressure is investigated. We performed measurements of high resolution (lifetime-broadening suppressed) X-ray absorption spectra and X-ray emission spectra based on inelastic X-ray scattering techniques for the pressure-induced spin and valence transition studies in materials.
