Abstract

Pr³⁺-doped Lu₃Al₅O₁₂ (LuAG:Pr) bulk single crystals were grown along the <100> direction by the vertical Bridgman method. The concentration distribution of Pr3+ over the crystal length was calculated and used to plot the dependence of the absorption coefficient at 582.3 nm (3H4 → ¹D₂) on the Pr3+ concentration. A concentration series of polycrystalline LuAG:Pr in the form of reacted powders was prepared under reducing atmosphere. Lattice parameters were measured in variously doped single crystals and reacted powders and used for estimation of the extent of non-equivalent substitutions by Lu³⁺ for Al³⁺ in octahedral lattice sites.
