Abstract

•Large CeAlO3 crystals are grown first time by the Czochralski and EFG techniques.•Transparent crystals are obtained by optimization of thermal annealing procedure.•Feasibility to obtain CeAlO3 crystal rods, plates, tubes, cylinders is shown.•Luminescence with decay times in the 38-43 ns range is observed at UV-excitation.

This study is focused on obtaining large CeAlO3 single crystals. Using Czochralski and Edge-Defined Film Fed Growth techniques, crystals of length up to 130 mm were obtained. The crystals belong to the tetragonal low temperature modification of CeAlO3, space group P4/mmm, a=3.7669 Å, с=3.7967 Å. Density and crystallographic parameters as well as some optical, luminescence and magnetic properties of CeAlO3 were studied. The crystals demonstrate rather bright luminescence under UV-excitation, while no luminescence has been registered under X-rays. Ceramic and single crystalline CeAlO3 samples demonstrate p-type conductivity and promising paramagnetic properties.
