ABSTRACT
ABSTRACT In the present work, a Raman spectroscopic investigation of the LnI3-CsI (Ln=Ce,Dy) binary systems is presented. Composition and temperature dependence of the Raman spectra of molten mixtures have been obtained. The changes of the vibrational modes upon melting the polycrystalline compounds Cs3LnI6 and Cs3Dy2I, have been measured. The data are discussed in terms of the liquid phase structure.
