Description

Bismuth Germanate Crystal Substrates Description 

BGO is an abbreviation for bismuth germanate. It is a cubic structure, colorless and transparent inorganic oxide crystal. It can emit green fluorescence with a peak wavelength of 480 nm under the excitation of high-energy particles and high-energy rays (x-rays, high-energy rays). BGO crystals have strong luminous properties at room temperature, high absorption coefficient, low afterglow, no deliquescence, and excellent energy resolution. It is a new generation of scintillation crystal material with excellent performance.

Bismuth germanate crystal substrate is a good photorefractive crystal with a wide range of applications. It is a light yellow photoelectric/electro-optical crystal and a photorefractive crystal. The BGO crystal can be used to detect X-rays, Y-rays, positrons and charged particles, and is widely used in high-energy physics, nuclear physics, nuclear medicine, nuclear industry and petroleum exploration.
