Bismuth germinate Bi4Ge3O12 commonly abbreviated as BGO, is the crystalline form of an inorganic oxide with cubic eulytine structure, colorless, transparent and insoluble in water. When exposed to radiation of high energy particles or other sources, such as gamma-rays, x-rays, it emits a green fluorescent light with a peak wavelength of 480nm, with its high stopping power, high scintillation efficiency, good energy resolution and non-hygroscopes, Our BGO is a good scintillation material and has found a wide range of applications in high energy physics, nuclear physics, space physics, nuclear medicine, geological prospecting and other industries.

1. DESCRIPTION
The Model YE2730 d33 meter is a special instrument directly to measure piezoelectric constant d33
values of piezoelectric ceramics, polymers, and single crystals. This meter can also measure d33
value in various single crystal materials, such as lithium niobate, quartz, and tourmaline. This
meter is capable of measuring d33 value over a very large range, at high resolution, and with a
high degree of reliability. The measurement is quickly, and easily made with a minimum of training
required. Specimens of a variety of sizes and shapes can easily be accommodated and measured.
For example: d33 value of disks, blocks, rings, tubes and semispherical shells can be easily
measured and displayed on the Model YE2730 d33 meter. Measuring d33 value is displayed on a 3
1/2 inch digital meter. This instrument is invaluable as a tool for quality assurance of piezoelectric
materials, production in-line inspection, or for research applications.

LYSO crystal is an ideal generation scintillator crystal. LYSO stand for Cerium doped Lutetium Yttrium Orthosilicate. LYSO crystal has the advantages of high light output, high density, fast decay time, good energy resolution and low cost. These properties mean that LYSO is an ideal candidate for a range of ray detection applications in nuclear physics and nuclear medicine, which require higher though improved timing resolution and superior energy revolution.
