最近，纳米多晶金刚石（NPD）砧已广泛应用于使用X射线吸收光谱（XAS）的高压研究。 NPD 砧中的纳米级多晶使我们能够获得无干扰的 X 射线吸收光谱。 NPD 砧座的这一优点极大地改善了 XAS 的实验条件，XAS 以前使用传统的单晶金刚石 (SCD) 砧座。由于 SCD 砧座的故障而导致的光谱失真一直是 XAS 不可避免的问题。本文回顾了最近使用 NPD 砧座进行的 XAS 和相关光谱技术的研究，这些研究主要是在 SPring-8 的 BL39XU 上进行的。我们演示了 NPD 砧在使用 XAS 进行高压研究时的用途。
Recently, nano-polycrystalline diamond (NPD) anvils have been widely applied in high pressure research using X-ray absorption spectroscopy (XAS). The nanometer-sized polycrystallization in NPD anvils enables us to obtain glitch-free X-ray absorption spectra. This advantage of NPD anvils drastically improves the experimental conditions of XAS, which has previously used conventional single-crystal diamond (SCD) anvils. Distorted spectra due to the glitches from the SCD anvils have been an inevitable problem of XAS. This paper reviews recent studies of XAS and related spectroscopic techniques using the NPD anvils, which have mainly been performed on BL39XU of SPring-8. We demonstrate how NPD anvils are useful when using XAS for high pressure research.
