摘要

我们测量了Sm2+:SrFCl中红宝石R1-和r2线以及5D0→7F0线的发光位移，对应于AIRAPT工作组推荐作为国际实用压力刻度(IPPS)的汞熔化压力。结果表明，Sm2+:SrFCl的R1-线、r2 -线和发光线的压力依赖性线性系数分别为0.3722±0.002、0.3796±0.002和1.123±0.002 nm/GPa。结果不仅严格限制了ruby和Sm2+:SrFCl压力表的初始斜率，而且还将基于发光的压力表与更基本的初级活塞压力表联系起来。

Calibration of ruby (Cr3+:Al2O3) and Sm2+:SrFCl luminescence lines from the melting of mercury: constraints on the initial slopes

ABSTRACT We have measured the luminescence shifts of the ruby’s R1- and R2-lines and the line of 5D0→7F0 from Sm2+:SrFCl corresponding to the melting pressure of mercury that is recommended by the AIRAPT task force as an International Practical Pressure Scale (IPPS). The linear coefficients of the pressure dependence of the R1-, R2-lines, and the luminescence line of Sm2+:SrFCl are determined to be 0.3722 ± 0.002, 0.3796 ± 0.002, and 1.123 ± 0.002 nm/GPa, respectively. The results not only put tight constraints on the initial slopes of ruby and Sm2+:SrFCl gauges, but also link the luminescence-based pressure gauges to the more fundamental primary piston gauges.
