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

Abstract The spatially dependent spectral-kinetic and crystal structure properties of undoped and Pr 3+ - doped LiY 1−x Lu x F 4 mixed crystals grown by Bridgeman technique were studied along crystal growth direction. The distribution coefficients of Pr 3+ , Y 3+ and Lu 3+ in these crystals were determined. The rise of lattice parameters with increasing of the Pr 3+ concentration along the crystal growth direction was observed.
