ABSTRACT High pressure energy-dispersive X-ray absorption spectroscopy is a valuable structural technique, especially, when combined with a nano-polycrystalline diamond anvil cell. Here we present recent results obtained using the dispersive setup of the ODE beamline at SOLEIL synchrotron. The effect of pressure and temperature on the X-ray induced photoreduction is discussed on the example of nanocrystalline CuO. The possibility to follow local environment changes during pressure-induced phase transitions is demonstrated for α-MoO based on the reverse Monte Carlo simulations.

ODE光束线高压X射线吸收光谱研究的最新进展

摘要 高压能量色散 X 射线吸收光谱是一种有价值的结构技术，尤其是与纳米多晶金刚石砧座结合使用时。在这里，我们展示了使用 SOLEIL 同步加速器的 ODE 光束线的色散设置获得的最新结果。以纳米晶 CuO 为例讨论了压力和温度对 X 射线诱导光还原的影响。基于反向蒙特卡罗模拟，证明了 α-MoO 在压力引起的相变期间跟踪局部环境变化的可能性。
