Pure, Pr3+, and Yb3+ doped Ca-fluoroapatite (Ca-FAP) crystals were grown by the Czochralski method. The effective distribution coefficient keff for Yb3+ was 0.5. For Pr3+ a very high keff of 1.4 was obtained. Values for keff are discussed in terms of an elastic model accounting for the strain energy originating from the difference in the size of Ln3+ ions. The Ln3+ concentrations were measured by absorbance spectroscopy, by inductively coupled plasma optical emission spectroscopy, and by electron microprobe analyses.
