Description
The diamond anvil cell is a well-established high-pressure technique that enables studies of small material samples at pressures exceeding multiple megabars. It is widely used for investigating strongly correlated systems, particularly at moderate pressures below 50 GPa and low temperatures.
While luminescence standards for pressure determination are well understood under ambient and high-temperature conditions, low-temperature studies rely primarily on Cr³⁺-doped Al₂O₃, which has limitations and conflicting calibration curves. This project will cross-correlate four luminescence-based pressure standards—Sm:YAG, SrBrO₄, Cr:Al₂O₃, and the novel AlB₄O₆N. The resulting insights will improve reproducibility and comparability in high-pressure, low-temperature experiments, but in particular in the fields of solid state physics.
