Czochralski growth and optical properties of Li6Gd1−xEux(BO3)3 (x=0-1) single crystals

It was shown that a continuous series of Li6Gd1−xEux(BO3)3 solid solutions exist within the whole concentration range (x=0-1). Li6Gd1−xEux(BO3)3 (x=0-0.03; 1) single crystals up to 25 mm in length and up to 20 mm in diameter have been grown by the Czochralski method. The structural perfection of the crystals has been estimated from etch patterns and XPA analysis results. The optical absorption and thermally stimulated luminescence of the grown crystals has been studied.
