The optical and scintillation properties of two sets of BGSO mixed crystals with Ge fraction varying from 0 to 100% were measured. A coincidence time resolution (CTR) at 511 keV of about 208 ps FWHM was measured for a 2x2x3 mm3 pixel with 40% Ge, while the optimum value obtained for the effective decay time is about 49.9 ns for a 6x6x0.7 mm3 plate-shaped sample with 30% Ge. Furthermore the smallest slow decay time component achieved is about 101 ns and is obtained for the plate-shaped sample with 30% Ge, while the largest is about 236 ns for a pure BGO sample with the same geometry.
