X-ray imagingScintillators, converting the absorbed high-energy X-ray photons into to visible ones, have been used in fields as medical diagnostics, radiation dosimetry, and security inspection. Commercial bulk scintillators generally suffer from time-consuming production, high-cost operation, and ...
Scintillators with high spatial resolution at a low radiation dose rate are desirable for X-ray medical imaging. To challenge the state-of-art technology, it is necessary to design large-area wafers with high light yield, oriented light transport, and reduced light scattering. Here, a seed-cry...

Transparent crystalline yttrium aluminum garnet (YAG; Y3Al5O12) is a dominant host material used in phosphors, scintillators, and solid state lasers. However, YAG single crystals and transparent ceramics face several technological limitations including complex, time-consuming, and costly synthetic approa...
X-ray imaginggarnetsbixbyitesWe report on the development of two new mechanically rugged, high light yield transparent ceramic scintillators: (1) Ce-doped Gd-garnet for gamma spectroscopy, and (2) Eu-doped Gd-Lu-bixbyite for radiography. GYGAG(Ce) garnet transparent ceramics offer 蟻 = 5.8...
In a previous paper an x-ray medical imaging system was described that used a liquid nitrogen cooled slow-scan CCD TV camera coupled to a Gd$-2$/O$-3$/(Eu) transparent ceramic scintillator plate with a high speed macro lens. This imaging system, which has a high spatial resolution and...
The dosimeter is composed of a lattice of scintillator fibers connected to a 64 channels photomultiplier tube. The detector combined with an appropriate electronics provides in real time an accurate measurement of the dose on the whole exposed surface. A linear relation between the photon count rate...
In the case of Tb31 ions, LaPO4:Ce31, Tb31, Gd2O2S:Tb31, and YBO3:Tb31 have been used in FLs, scintillators, and PDPs, respectively2,5. Thus, many studies have been published on Eu31- and Tb31-activated inorganic crystals, which are known as phosphors2–6. In 1999, Meijerink...
