Phase-change materials and chalcogenides

Arguments are presented justifying the use of fluoride optical basicity values (e.g. λ (BaF2) = 0.50, λ (SiF4) = 0.21, λ (ZrF4) = 0.38) for calculating the optical basicity of all-fluoride and oxide/fluoride glasses. The resulting λ values agree with those obtained by probe ion spectroscopy, and provide a means for calculating trends in ideal optical basicity for glass systems such as BaF2ZrF4 or AlF3Al(PO3)3.
