“…A scintillator is a special category of phosphor material that has a very unique ability to convert ionizing radiation such as X-and γ-rays to lower energy photons such as ultraviolet and visible light [1,2]. In particular, the solid scintillators come in many forms of materials, including plastics [3,4], glass [5][6][7], transparent ceramics [8,9], inorganic-organic perovskite [10,11], and single crystals [12][13][14]. Generally, these scintillators are combined with photodetectors such as photomultiplier tubes, silicon photomultipliers (SiPMs), or photodiodes.…”

Five samples of lanthanum pyrosilicate (La2Si2O7) single crystals with 0.5–10.0% Praseodymium (Pr)-doping concentrations were synthesized by the floating-zone method. Photoluminescence and scintillation properties of these crystals were investigated in this study for the first time. The multiple emissions from electron transitions of Pr3+ were observed on both a photoluminescence emission map and scintillation spectra, including the desired emission band of Pr3+ 5d–4f transition at 250–310 nm. The major photoluminescence and scintillation decay times were approximately 19 and 26 ns, respectively. When compared with commercial scintillators such as Tl-doped cesium iodide (CsI), the Pr-doped La2Si2O7 samples presented a respectively low afterglow level of 32 ppm after 20 ms of X-ray irradiation. Under 662 keV γ-ray irradiation from 137Cs, the 3.0% Pr-doped La2Si2O7 sample presented a scintillation light yield of 3200 ph/MeV, which was the best value among the tested samples.

“…In this research situation, a large number of new glasses have been studied for ionizing radiation detectors. [29][30][31][32][33][34][35][36][37][38][39][40] In the current study, we focused on commercial luminescent glasses, namely, Lumilass-G9 and -R7 by Sumita Optical Glass. Lumilass glasses were developed for general luminescent purposes, and luminescence colors of blue (Luminass-B), green (Lumilass-G9), and red (Lumilass-R7) were commercialized.…”

Commercial phosphor glasses, namely, Lumilas-G9 and -R7 were investigated on their optical and scintillation characteristics. In transmittance, close to 90% transmission was achieved in both glasses at visible wavelength, and some specific absorption lines due to 4f-4f transitions of Tb3+ and Eu3+ were detected in Lumilass-G9 and -R7, respectively. In photoluminescence and scintillation, several sharp emission lines were observed in both glasses, and the emission origins of them were attributed to 4f-4f transitions of Tb3+ and Eu3+. Under pulse X-ray irradiation, scintillation decay time of both Lumilas-G9 and -R7 resulted 1.3 ms. To determine the scintillation light yield, α-rays from 241Am were irradiated to these samples, and the light yields of Lumilas-G9 and -R7 estimated by pulse area measurements turned out to be 700 and 1800 ph/MeV, respectively.
