Pressure dependence of Raman scattering by chromium-doped halide elpasolite crystals

Effects of High Pressure on the Luminescence and Upconversion Properties of Ti2+-Doped NaCl

“…This compares to pressureinduced shift rates for e g vibrational energies of ∆ν j eg ) 0.55 cm -1 /kbar for CrCl 6 3in Cs 2 NaScCl 6 and ∆ν j eg ) 1.1 cm -1 / kbar for CrF 6 3in K 2 NaScF 6 . 34,35 Thus, the slightly lower value for ∆ν j eg in our system reflects the relatively low effect pressure has on the TiCl 6 4in NaCl, i.e., this is in line with the low χ loc value discussed above.…”
