摘要：

Single crystals of bismuth silicate were grown by the Bridgman method. The excitation and emission spectra are similar to BGO. The light output is 20% of BGO, giving FWHM energy resolution of 319b for 662 keV gamma-rays (Cs-137). The decay constants are 2.4 ns (for 6% of intensity), 26 ns (12%) and 99 ns (82%). The radiation hardness against Co-60 gamma-rays was about 10(5)-10(6) rad at the emission peak of 480 nm. Spontaneous recovery as well as optical annealing was also studied. BSO may be one the promising scintillators for high energy physics experiments.
