Eu 2+ and Mn 2+ co-doped Lu 2 Mg 2 Al 2 Si 2 O 12 phosphors for high sensitivity and multi-mode optical pressure sensing

The Eu 2+ and Mn 2+ co-doped Lu 2 Mg 2 Al 2 Si 2 O 12 phosphor has two independent high sensitivities, 1.77 and 3.53 nm GPa −1 . The decay degree of the overall integral intensity and the fluorescence intensity ratio (FIR) were put forward for pressure sensing.
