- Calcium fluoride crystals doped with various concentrations of $PbF_{2}$ have been grown using the Bridgman technique. The optical absorption spectra reveal the characteristic UV absorption bands of the $Pb^{2+}$ ions. The distribution of the $Pb^{2+}$-ions along four crystals has been investigated using the optical absorption method. Taking into account the relationship between the optical absorption coefficient and the concentration of the impurities in the samples, the effective segregation coefficient of the $Pb^{2+}$ ions has been calculated. Our study shows that the effective segregation coefficient of the $Pb^{2+}$ ions in $CaF_{2}$ host depends on the dopant concentration, and varies between 0.85 and 1.15, for 0.5 mol%$PbF_{2}$ and 3 mol%$PbF_{2}$-doped $CaF_{2}$, respectively.
