BGO Scintillators
BGO scintillation crystalis one of the most common oxide scintillation materials. It exhibits stable physical and chemical properties, high mechanical strength, high density, high refractive index, and resistance to harsh environments. With its high stopping power, high scintillation efficiency, good energy resolution and non-hygroscopic, BGO is a good scintillation material for a wide range of applications in high energy physics, space physics, medicine, geological exploration and other industries.
OST Photonics can supply BGO crystals, BGO arrays and BGO scintillation detector upon request. We can offer a variety of design options and reflector materials to optimize array performance and ensure the array's high light output, excellent uniformity and minimal crosstalk.
