基于微米级金刚石的基本拉曼谱带随压力的变化，提出了一种新的拉曼压力标度。首先，我们证实了三重简并金刚石声子的压力斜率的行为在一个类似的方式，散装。我们的测量校准拉曼对Sm：YAG荧光压力规模高达5 GPa使用衬垫蓝宝石砧室。最相关的特点，关于设计的砧座细胞简要概述。测量在流体静力学条件下进行，使用4：1的甲醇-乙醇作为压力传递介质。根据关系式p（GPa）= 0.356[ν（cm-1）-1332.3]的校准压力被认为在约0.1GPa内是精确的。用几个例子证明了在使用宝石砧装置的拉曼研究中使用微米级金刚石作为压力传感器的方便性。版权所有© 2003年约翰威利父子有限公司。
We propose a new Raman pressure scale based on the shift with pressure of the fundamental Raman band of micrometer-sized diamonds. First, we confirmed that the pressure slope of the triply degenerate diamond phonon behaves in a similar fashion to that of the bulk. Our measurements were calibrated Raman against the Sm:YAG fluorescence pressure scale up to 5 GPa using a gasketed sapphire anvil cell. The most relevant features regarding the design of the anvil cell are briefly outlined. Measurements were performed under hydrostatic conditions using 4 : 1 methanol–ethanol as pressure-transmitting medium. The calibration pressures according to the relationship p(GPa) = 0.356[ν(cm−1) − 1332.3] are considered to be accurate within about 0.1 GPa. The convenience of using micrometer-sized diamonds as pressure sensors in Raman studies using gem anvil devices is demonstrated with several examples. Copyright © 2003 John Wiley & Sons, Ltd.
