本文采用坩埚下降法生长出20mm×20mm×100mm优质Bi₄Si₃O₁₂及Fe、Cr掺杂Bi₄Si₃O₁₂晶体．测试了晶体的透射光谱、能谱及光产额、FWHM能量分辨率和激发一发射光谱．总结并解释了掺杂影响Bi₄Si₃O₁₂晶体闪烁性能的规律．

High optical quality Bi₄Si₃O₁₂ and Fe, Cr doped Bi₄Si₃O₁₂ single crystals with the size 20mm×20mm×100mm were grown by the vertical Bridgman method. After measuring their trans.mission spectra, relative light output, FWHM energy resolution, excitation spectra and emission spectra, the laws of the doped effects on scintillation properties of Bi₄Si₃O₁₂crystals were summarized and explained.
