Abstract
Refractive index dispersion parameters of optical crystals of MFn (Mn+ = Na+, K+, Ca2+, Sr2+, Ba2+, Cd2+, Pb2+, La3+, Ce3+, Pr3+, Nd3+) binary fluorides have been shown to correlate with the cation coordination numbers in their structures. Using this correlation, I have demonstrated that, with increasing LaF3 concentration, the cation coordination number in Sr1 −xLaxF2 +x ternary fluoride crystals (fluorite structure) increases from 8 to 11.
