Abstract
The Bridgman growth of bismuth silicon oxide (BSO) crystals along 〈001〉, 〈110〉, 〈111〉 and 〈112〉 directions is reported in this paper for the first time. The mechanism of the darkened core formation in the Bridgman grown BSO crystals has been clarified on the basis of the investigation of the Czochralski growth of BSO. The possibility of the mass production of the core-free BSO crystals with high optical quality by the Bridgman method along 〈111〉 and 〈112〉 growth directions has been expounded.
