Development of the HiLightTM scintillator for computed tomography medical imaging

Synthesis and optical characterization of SrHfO3:Ce and SrZrO3:Ce nanoparticles

“…Ceramic mixed oxides for scintillation purposes have been developed on various materials such as YAG:Ce [4] or (Y,Gd) 2 O 3 :Eu [5]. Perovskites AMO 3 :Ce (A = Ca, Sr, Ba and M = Zr, Hf) have also been investigated, for various powder preparation methods [6][7][8].…”

Optical, luminescence, and scintillation properties of ZnO and ZnO:Ga ceramics

“…Crystals of cubic syngony are most acceptable for producing optical ceramics ͑ceramics that are transparent to their own radiation͒. 6 It is much harder to obtain a transparent ceramic in the visible region in the case of crystals with low symmetry ͑such as ZnO͒, since microstructure is formed from the disoriented grains during the hot pressing of an optical ceramic, and this causes significant light scattering even when the refractive-index difference ͑⌬n͒ is insignificant. The negative influence of ⌬n can be minimized by making the predominant orientation of the grains coincide with the direction of the optic axis.…”

Evaluating optical spectral matching of phosphor-photodetector combinations

“…These data were corrected for the optical response of the monochromator and the background in order to diminish any systematic errors. Additional inherent optical photon energy distributions for various phosphors (LaCl 3 :Ce with dopand concetration 0.1%, CdS:In, CdS:In, Te, CdS:Te, HiLight T M ), where obtained from literature [8][9][10]. The corresponding values of, E eλ var [E] eλ , E iλ and var [E] iλ were calculated according to previous studies [3,4].…”
