Above 7 GPa, visible luminescence is observed when argon in a diamond anvil cell is irradiated by high energy x rays from a synchrotron source. The spectrum consists of two peaks which shift by −43.6±0.7 cm−1/GPa and −47.5±2.4 cm−1/GPa from ambient pressure emission energies of 17 900±40 and 17 300±140 cm−1, respectively. These shifts are linear up to 60 GPa and reversible on decompression. Extrapolation of the shifts to ambient pressure suggests that this is a 4p–5d atomic transition. © 2000 American Institute of Physics.
