Our optical grade undoped Czochralski grown monocrystals bismuth germanate crystal substrates with high optical homogeneity excluding the central core of crystal boules, without visible striae with shadowgraph, inclusions, and bubbles.
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.
