“…Cathode luminescence properties were reported by Takeda et al [ l l ] in 1980 and later by Autrata et al [12] in 1983. The optimum Ce3+ concentration is near 0.2 weight% [65]. The emission of YA103(Ce3+) at 360 nm and the light yield depends slightly on the method of crystal growth [66].…”

Abstract-A review and new data are presented on the absolute photon yield emitted by "classical" (NaI(Tl+), CsI(Tl+), CsI(Na+), CaF2(Eu2+);+BigGe30n, and CdW04) and "modern" (BaF2, GdzSiOs(Ce ), Y A l o~( c e~+ ) , Lu2Si05(Ce3+), Lu3 A15 0 1 2 (Sc3+), and K2LaCl5 (Ce3+)) scintillation crystals after absorption of X-rays and y-rays of energies ranging from 5 keV to 1 MeV. Factors influencing the energy resolution with which high energy photons can be detected with scintillatorphotomultiplier combinations are reviewed. Attention is especially focused on the effects of nonproportionality in the scintillation response on the energy resolution.

“…The optimum light yields result from the addition of 0.1 to 0.5 wt % CeO 2 [7] without changing the decay time. They Manuscript received August 9, 1999 are of high hardness (8.6 Mohs), chemically inert, nonhygroscopic, not soluble in acids, and resistant to alkali.…”

“…YAP monocrystals as X-ray detectors have been studied some years ago by Mares et al [5], [6]. Excited by X-rays, the scintillation decay time of YAP is with 27 ns [7], about one order of magnitude shorter than with other inorganic radiation detectors.…”

Abstract-A YAP(YAlO 3 : Ce)-scintillating window, coated on its inner surface with an S20-photocathode, seals a cross-focusing hybrid photomultiplier tube (HPMT) equipped with a small p-i-n anode of 2-mm diameter. This new radiation detector separates X-ray lines down to about 2-keV peak energy from the HPMT noise. Its detection efficiency for high gamma energies depends on the YAP-window thickness and amounts to about 18% attenuation at 400-keV energy in the present version. Competitive radiation detectors like silicon photodiodes and silicon drift chambers are discussed and compared to our prototype, with particular attention given to their energy resolution and noise performance, which limits their active area considerably.

“…For the moment, typical light yield of mass-produced YAP : Ce crystals is 14 500 ph/MeV [21]. However, light yield obtained from LuAP : Ce samples is not more than 9000 ph/MeV and is strongly dependent on technological factors.…”

Abstract-As already advertised for several years, Lu-based compounds doped with trivalent Ce seem to be the most promising scintillators for a new generation of positron emission tomography scanners. Two crystals, namely LSO : Ce and LuAP : Ce, are under intensive study, but there is still an interest in searching for materials with a better combination of price/performance. In the study reported in this paper, we paid attention to the compounds containing rare earth and Ba, Hf. Another motivation was an increase of the effective charge of the host matrix and a decrease of the Lu fraction in compound. In this paper, we discuss spectroscopic properties of several new heavy compounds such as Lu 2 Hf 2 O 7 , La 2 Hf 2 O 7 and Ba 3 Lu 4 O 9 doped with Ce.
