论文摘要
高压能量分散性X射线吸收光谱是一种有价值的结构技术，尤其是与纳米聚晶型钻石小动脉细胞结合使用时。在这里，我们介绍了使用Soleil同步子处的Ode Beamine的色散设置获得的最新结果。在纳米晶CuO的示例中，讨论了压力和温度对X射线诱导的光量的影响。基于反向蒙特卡洛模拟，证明了在压力诱导的相变时遵循本地环境变化的可能性。
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 alpha-MoO3 based on the reverse Monte Carlo simulations.
