红宝石发光法被广泛应用于金刚石压砧和其他光学透明压力容器的压力测量。考虑到这一应用，我们简要地回顾了α-Al_2O_3的基态物理性质，重点是它在高压下的行为，调查了温度和应力对红宝石（Cr掺杂的α-Al_2O_3）的R线发光的影响，并解决了最近的努力，以改善在超过50 GPa的静水压力下的R线位移的校准。
The ruby luminescence method is widely used for pressure measurement in the diamond anvil cell and other optically transparent pressure cells. With this application in mind, we briefly review the ground-state physical properties of corundum (α-Al2O3) with some emphasis on its behavior under high pressure, survey the effects of temperature and stress on the R-line luminescence of ruby (Cr-doped corundum), and address the recent efforts towards an improved calibration of the R-line shift under hydrostatic pressures beyond the 50 GPa mark.
