BGO is the crystalline form of an inorganic oxide with a cubic
eulytine structure. It is transparent and insoluble in water.
When exposed to irradiation, such as gamma-rays or X-rays, it
emits a green fluorescent light with a peak wavelength of
480nm. It is characterized by high stopping power, high
scintillation efficiency, and good energy resolution. It is also
non-hygroscopic. BGO is a good scintillation material and
has found a wide range of applications in nuclear medicine,
security, high energy physics, nuclear physics, space physics,
and geological exploration.
