Thallium activated Cesium Iodide or CsI(Tl) crystals is one of the brightest scintillator. The maximum of the broad emission situated at 550nm is is well suited for photodiode readout. It has excellent mechanical properties, with a light yield four-times higher than that of BGO and a radiation length shorter than that of NaI(Tl). CsI(Tl) is slightly hygroscopic with plastic mechanical properties. Combined with the relatively good radiation hardness properties, CsI(Tl) is well suited for High Energy Physics.

Cerium doped Silicate Yttrinm YSO(Ce) has an emission maxiimum at 420nm which belongs to monoclinic rare earth orthosilicate crystal. it has similar decay time with LYSO(Ce) (50-70ns), but it has no background(Lutecium), which need to be removed in some precise detection field.

BGO crystal is one of the most widely used scintillation materials of the oxide type. It has a high Z, high density scintillation material. Due to the high atomic number of bismuth (83) and the material's high density of 7.13 g/cm3, BGO is a very efficient gamma ray absorber. Given the high Z value of the material, the photo fraction for gamma ray absorption is high, as a result very good peak-to-total ratios are observed. Due to these features, BGO crystals are used in high-energy physics (scintillators for electromagnetic calorimeters and detecting assemblies of accelerators), spectrometry and radiometry of gamma-radiation, positron tomography.

With the wavelength of the maximum emission at 560nm,YAG(Ce) can well matched to CCD sensitivity. And it is known as a kind of non-hygroscopic, chemically inert inorganic scintillation material. Ce:YAG is a reasonably fast scintillator with a relative light yield of 12% of NaI(Tl). Yag(ce) scintillators are used in SEM, electronic imaging, beta-ray and X-ray counters and imaging. It has excellent temperature and mechanical characteristics which makes it suitable for ultra-thin screen of <0.005mm. Ce:YAG crystals has a high threshold for high energy electrons or ions, makes it suitable for high electric current environment.

Cerium doped yttrium aluminum (or Ce:YAP) crystals is a type of fast scintillating materials, it is mechanically strong and chemically inert, suitable for precise mechanical fabrications. A very thin aluminum layer film could be deposited on the entrance surface to avoid the light-sensitivity. YAG(Ce) can well suit for imagining applications due to its ultra-low energy secondary X-ray emmissions. Ce:YAP detectors are widely used in the field of gamma and X-ray counting, electron microscopy, electron and X-ray imaging screens, and computer tomography systems.
