Structural features and distribution coefficients of Pr3+, Y3+ and Lu3+ ions in LiY1−xLuxF4 mixture crystals

The spatially dependent spectral-kinetic and crystal structure properties of undoped and Pr3+ - doped LiY1−xLuxF4 mixed crystals grown by Bridgeman technique were studied along crystal growth direction. The distribution coefficients of Pr3+, Y3+ and Lu3+ in these crystals were determined. The rise of lattice parameters with increasing of the Pr3+ concentration along the crystal growth direction was observed.
