Abstract
AbstractMicro‐Raman spectroscopy has been used to measure first‐order Raman spectra from selected volumes in diamonds under pressure in a high‐pressure diamond‐anvil cell in both the 180° and 135° scattering geometries. The high‐frequency component of the diamond line at the diamond‐sample interface is found to shift linearly with pressure and exhibits a pressure coefficient of 0.237 cm−1 kbar−1. This shift of the diamond line could be used for pressure determination. The Raman spectra from selected volumes of the diamond anvil at various depths provide useful information about stress distribution in the anvil.
