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 pressureinduced spin and valence transition studies in materials.
