Optical spectroscopy at cryogenic temperatures using a Block-Piermarini diamond-anvil cell

A simple experimental setup allowing low‐temperature high‐pressure spectroscopy, with in situ pressure adjustment, is described. A Block–Piermarini diamond‐anvil cell is used together with standard laboratory materials. Results of semiconductor photoluminescence studies, using argon as a pressure‐transmitting medium, are given as an illustration and are also used for the study of the pressure conditions. Pressure homogeneity is better than 100 MPa up to 6 GPa, and the residual uniaxial component of the stress can be lower than 100 MPa.
