摘要: 本文介绍了作者利用国内加工的金刚石压砧装置及组建的微区光谱系统进行100 GPa（百万大气压）准静水压光谱学实验的概况，证明压力产生装置和微区光谱系统的多功能性是充分可靠的。实验中遇到的压力产生能力超过压力测量能力的事实，反映了高压光谱学实验在压力范围扩大时所遇到的挑战。文中对高压下的拉曼、发射、吸收及反射光谱的实验原理和实验方法也作了概略的介绍。Abstract: A multifunctional spectroscopic system for high pressure experiments using diamond anvil cell has been established. It was used for optical absorption, reflectance, luminescence, and Raman scattering experiments, and a highest quasi-hydrostatic pressure of 126.5 GPa has been obtained for absorption experiment of ordinary liquid nitrogen. Authors represent a fact that gasketed diamond anvil cell with beveled anvils and gas pressure medium shows a pressure generating capability much higher than 126.5 GPa, and the challenging problem is inefficient ruby fluorescence method of pressure measurement under high pressure.
