Hydrostatic pressures of up to 200kbar have been employed to influence the spectroscopic properties of MgF2 doped with divalent ytterbium. MgF2:Yb2+ exhibits a broad band emission peaked at 485nm related to the 4f135d1→4f14 transition of Yb2+. At pressures between ambient and 92kbar, a red-shift of the luminescence maximum was observed, whilst simultaneously the decay time of the emission gradually...
