Scintillation properties

TPX is considered a high temperature host polymer, which provides scintillator properties. A modified TPX is manufactured under the brand name THERMOSCIN. The material is temperature resistant and has a relatively high hydrogen content as compared to a conventional scintillation material (20). 

By far the most important application of oxazoles is based on the scintillator properties of 2,5-diaryloxazoles (B-70MI41800). Diaryl- and arylstryryl-oxazoles are fluorescent whitening agents, and 2-arylbenzoxazoles are used as dye lasers (B-75MI41800). 

The scintillation properties of 1,3,4-oxadiazoles have been particularly intensively investigated since 1955.154,175-191 Liquid and plastic... 

It allows the existence of the scintillating properties of BaF2 crystals a wide forbidden band is necessary for avoiding reabsorption of the ultraviolet 2pF —> 5pBa emission produced when holes are formed in the 5pBa core levels by X-rays or y-rays (cross-luminescence) [3],...

In the method of delayed coincidences, the coincidence counting rate between detectors responding selectively to genetically related particles, e.g., a jS- or a-par-ticle and a y-ray or an electron or between y-rays, is plotted as a function of a time delay inserted in the electronic circuits used to detect one of them. The development of this method and of improved electronic techniques has led to the use of resolution times of between 10" and 10 sec. We shall not discuss these methods here, for they have been very adequately reported by Bell [i9], 2ff]. Further analysis of the experimental data has made it possible to measure lifetimes of the order of 10 sec. The limit to the method seems to be determined by the scintillating properties of the phosphor and its physical size. 

Nevertheless, sensor materials based on inqnegnated fluors and extractants exhibited limited long-term stability in (heir scintillating properties. This pronqited us to explore an alternative approach for developing preconcentrating minicolumn sensors. Scintillation and chemical selectivity were combined in a conqiosite sensor column by creating an intimate mixture of separate solid phase... 

The absolute detection efficiency of the con osite sensor column was 34% and analyte recovery (loading efficiency) was 97%. The Tc(VII) selective conq>osite bed sensor can be regenerated using a small volume of 2 M nitric acid solution, resulting in rapid elution of the retained analyte without loss of the scintillation properties.

However, it was observed that, as new scintillators, these complex perovskite ceramics have a dilFerent thermal quenching effect, as compared to the conventional scintillator materials, which deserves further investigation in the future. Figure 10.8 shows a photograph of the perovskite transparent ceramic samples, with a thickness of 2 mm [123]. Optical properties, including transmittance, photoluminescence, and photoluminescence decay time, have been characterized. Scintillation properties, such as radioluminescence and pulse height spectra, were studied in details.

Single crystals of a size up to 10 mm of CsGd2p7 and CSY2F7 doped with Ce " have been grown imder hydrothermal conditions. Scintillation properties have been measured (Schaart et al. 1995). However, the light yield after high energy irradiation (662 keV) is low.

The scintillation properties of LaCl -.Ce and LaBvs.Ce crystal were discovered in 1999 [1] and in 2001 [2] respectively and commercialized by St. Gobain with the name of Brillance 380 (LaBrs. Ce) and Brillance 350 (LaCls.Ce). The numbers 350 and 380 indicate the values of the wavelength of the emitted scintillation light) [3,4]. The first cylindrical large volume 3" x 3" crystals was produced approximately in 2006. In 2007 it was possible to reach the size of 3" x 6" while one year later the first 3.5" x 8" detector was delivered [5-7].
