Raman Scattering from Mixed Crystals (CaxSr1−x)F2 and (SrxBa1−x)F2

Abstract

The first-order Raman spectrum of mixed crystals of ${\mathrm{Ca}}_x{\mathrm{Sr}}_{1-x}{\mathrm{F}}_2$ and ${\mathrm{Sr}}_x{\mathrm{Ba}}_{1-x}{\mathrm{F}}_2$ has been measured. The Raman frequency varies linearly with concentration, while the Raman linewidth exhibits a maximum near the 50% mixture.
