摘要：
Recent results of the application of the low-thermal-gradient version of the Czochralski technique (LTG Cz) for growth of top quality, water-transparent, radiation hard large sized Bi4Ge3O12 (BGO) crystals is considered. Boules up to 130 mm in diameter and 400 mm in length are currently growing. At lambda = 480 nm, the attenuation length of the material in the main part of the boule reaches 10 m or more.
