Luminescence kinetics of the LiSc(WO 4 ) 2 crystals doped with trivalent chromium has been investigated by high-pressure spectroscopy in the pressure range from ambient to 227kbar, at temperatures from 20K to room. For pressure range146–181kbar we observed that pressure induced the structural transformation where the broad band emission related to 4 T 2 → 4 ...
We report the results of high-pressure studies of spectral properties in Cr 3+ -doped LiSc(WO 4 ) 2 crystals between ambient pressure and 260kbar. The effect of pressure on the present system has led to a structural transformation for pressure 60–88kbar and a low-field → high-field spectral transformation of the Cr 3+ emission for pressure 117–227kbar. The pressure-induced...
