Abstract
As a multifunctional opto-electro material, Bi 12 GeO 20 crystal shows high-speed photorefractive response in visible range, excellent piezoelectric, acousto-optic, magneto-optic, optical rotation, and electro-optic properties, etc.Presently, Czochralski (Cz) method, which is commonly used to grow Bi 12 GeO 20 crystals, has several bottle-necks, such as high growth cost, irregular crystal boule shapes, low growth yield, poor optical quality in large crystals, and small effective crystal cross-sectional area.In this study, large Bi 12 GeO 20 crystals were firstly grown by using modified vertical Bridgman method in platinum crucibles and air atmosphere.Morphology, distribution, and constitutes of main macroscopic defects in as-grown Bi 12 GeO 20 crystals were investigated, and the formation process and causes of the
