A rapid, convenient technique for precision pressure measurement in the diamond-anvil high-pressure cell, which makes use of the sharp-line (R-line) luminescence of ruby, has been developed. The observed shift is -0.77 �0.03 reciprocal centimeters per kilobar for R1 and -0.84� 0.03 reciprocal centimeters per kilobar for R2 to lower energy and is approximately linear in the range studied (to 22 kilobars). Line-broadening has been observed in some instances and has been tentatively identified… 

Calibration of the Ruby-Pressure-Scale at Low Temperatures

Development and accurate calibration of the ruby manometer [1–4] led to rapid progress in diamond anvil cell high-pressure techniques [5]. Applications of the ruby manometer at low temperatures [6],

Ruby under pressure

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

Ruby thermometer for cryobaric diamond‐anvil cell

The ruby R‐line luminescence, commonly used as a manometer in diamond‐anvil cell experiments, is shown also to be a useful thermometer over the range 10–100 K. Measurements up to 120 kbar in a solid

Ruby pressure scale in a low-temperature diamond anvil cell

Laser-excited N and R fluorescence lines of heavily doped ruby have been studied up to 26 GPa at low temperatures. While the intensity of the R lines at ambient pressure significantly decreases with

A gasketed diamond-anvil high-pressure cell is described which can be used on a four-circle automatic diffractometer to collect x-ray intensity data from single-crystal samples subjected to truly

Ultrahigh pressure diamond‐anvil cell and several semiconductor phase transition pressures in relation to the fixed point pressure scale

A diamond‐anvil type optical cell of improved design has produced static pressures in gasketed samples up to 500 kilobar as measured by the ruby fluorescence technique. The ruby R1 line pressure

Spectroscopy at very high pressures. X. Use of ruby R-lines in the estimation of pressure at ambient and at low temperatures

The effect of pressure at low temperature (166.8K) upon the R1 and R2 lines of ruby has been investigated for the first time to establish a calibration for use in high-pressure/low-temperature work.

Note: a portable, light-emitting diode-based ruby fluorescence spectrometer for high-pressure calibration.

Here, a simple, robust, and portable design that employs light-emitting diodes (LEDs) instead of laser sources is presented, which is safer in comparison with laser-based ones.

Ruby fluorescence pressure scale: Revisited

Effect of non-hydrostatic stress on X-ray diffraction in a diamond anvil cell (DAC) is studied. The pressure gradient in the sample chamber leads to the broadening of the diffraction peaks, which



X‐Ray Diffraction and Optical Observations on Crystalline Solids up to 300 kbar

Diamond anvils driven by a simple piston and screw device have been used to subject solid samples to pressures up to 300 kbar at ambient room temperature. Samples can be examined optically and by

Instrumentation for Single Crystal X‐Ray Diffraction at High Pressures

A diamond anvil high pressure cell made of beryllium, a special goniometer head, and a Buerger‐type precession camera designed for x‐ray diffraction by single crystals at high pressures are described

Polymorphism in Benzene, Naphthalene, and Anthracene at High Pressure

Optical observations were carried out on benzene, naphthalene, and anthracene up to temperatures of about 600�C and pressures of approximately 40 kilobars, and the existence of the high-pressure polymorph, n Aphthalene II, was verified.

Allotropy in Some Rare-Earth Metals at High Pressures

Allotropes of lanthanum, cerium, praseodmium, and neodymiumc have been observed at elevated pressures with an x-ray diffraction camera which incorporates a diamondanvil, high-pressure cell which has a face-centered cubic structure.
