Abstract
- Abstract: Nd, Ho, Er, and Tm doped lutetium aluminum garnet (LuAG) single crystals were grown using the micro-pulling down (μ-PD) method. The crystals were produced from the melts containing 3mol% of the dopants. The axial and radial dopant distribution were measured by electron probe micro analysis. Nd3+ and Ho3+ ions concentrated in the rim (k 0<1) and the radial concentration showed concave curvature. k 0 is the segregation coefficient of the dopant with respect to the given host phase. In the case of Er3+ and Tm3+ ions, the k 0 value is considered to be nearly 1 and the radial dopant distribution profiles were almost flat. [Copyright &y& Elsevier]
