## Abstract Using the micro‐pulling‐down method, (Ce,Sr)‐doped PrAlO~3~ square‐shaped single crystals (4×4×12 mm) were grown. Structural parameters studied by X‐ray powder diffraction were consistent with R3m space group. Compositional homogeneity was checked with electron probe micro‐analysis and
Single crystals of lithium niobate doped with 0.03 and 0.1 at.% of Cu or Fe ions were grown by the Czochralski technique. Optical absorption spectra in visible and infrared regions before and after γ irradiation with doses up to 10 5 Gy were measured and positions of both dopants in LiNbO 3 lattice
Single crystals of GdCa 4 O(BO 3 ) 3 (GdCOB) pure and doped with Eu concentration of 1 and 4 at% were grown by the Czochralski and micropulling-down methods. The distribution of Eu ions in GdCOB crystals was uniform. The substitutions of Eu 3+ in Gd, Ca(1) and Ca(2) cation sites and eventually forma
