Abstract
Single crystals of bismuth silicate were grown by the Bridgman method. The excitation and emission spectra are similar to BGO. The light out put is 20% of BGO, giving FWHM energy resolution of 319b for 662 keV g amma-rays (Cs-137). The decay constants are 2.4 ns (for 6% of intensit y), 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. S pontaneous recovery as well as optical annealing was also studied. BSO may be one the promising scintillators for high energy physics experi ments.
