Abstract:

Using stoichiometric Si(OC2H5)4 and Bi(NO3)3·5H2O as precursors and citric acid as solvent, polycrystalline Bi4Si3O12 (BSO) powders were synthesized by Sol-Gel method and sintered at high temperature. Batch production of 250 g powders was realized. Using as-synthesized BSO powders and <001>-oriented BSO seeds, BSO crystals were grown in the vertical Bridgman furnace. The crystallization behavior was discussed and high quality BSO crystal up to 30 mm × 30 mm × 210 mm was obtained. The scintillation characteristics of BSO single crystals were investigated. The energy resolution of the BSO crystal was 18.9% and the relative light yield of the crystal was 7.2% compared with CsI(Tl) at the same conditions.

Key words: Sol-Gel method, Bi4Si3O12 crystal, vertical Bridgman method, crystal growth, scintillation property
