Product introduction
Introduction and application of Gadolinium Oxysulfide | CAS:12339-07-0
Specification of Gadolinium Oxysulfide | CAS:12339-07-0
The main use of GdO2S is in ceramic scintillators. Scintillators are used in radiation detectors for medical diagnostics. Scintillators are primary radiation sensors that emit light when struck by high energy photons. The final density of GdO2S based ceramics is 99.7% to 99.99% of the theoretical density (7.32 g/cm3) and the average grain size ranges from 5 microns to 50 microns, depending on the manufacturing process.
Two powder preparation routes have been successfully used to synthesize GdO2S: Pr, Ce, F powder complexes for ceramic scintillators. These preparation routes are called halide flux method and sulfite precipitation method. The scintillation properties of GdO2S: Pr, Ce, F complexes show that this scintillator is promising for imaging applications. There are two major disadvantages of this scintillator; one is the hexagonal crystal structure which gives optical translucency and low external light collection only at the photodiode. The other disadvantage is high X-ray damage to the sample.
Terbium-activated gadolinium oxysulfide is often used as a scintillator for X-ray imaging. It emits between 382-622 nm, but the main emission peak is at 545 nm. It is also used as a green phosphor in projection CRTs, but has the disadvantage of significantly reducing its efficiency at higher temperatures. Variants include
