Thermally stimulated luminescence (TSL), optically stimulated luminescence (OSL), and radio-photoluminescence (RPL) are radiation-induced luminescence phenomena, and they are widely used for radi ... Read More

In the neutron irradiation field in boron neutron capture therapy, neutron rays and γ-rays are mixed, and it is not easy to selectively measure only neutron rays. The currently used gold activat ... Read More

The scintillation properties of organic–inorganic layered perovskite-type compounds were analyzed using pulsed beams having different linear energy transfers (LETs). Initially the decay was slo ... Read More

We evaluated the nonradiative deactivation in three scintillators, Gd2SiO5:Ce (GSO), Lu2−xGdxSiO5:Ce (LGSO), and Lu2−xYxSiO5:Ce (LYSO), using a photoacoustic spectroscopy technique (PAS). The ... Read More

Manganese-doped zinc phosphate (MnZP) glasses were prepared in Ar and air to examine the relationship between the physical properties and preparation atmosphere. The glass transition temperatures ... Read More

In this paper, we evaluated the Ag concentration dependence of the build-up effect of radio-photoluminescence (RPL) in Ag-doped P2O5–Al2O3–Na2O–SiO2 (PANS) glasses. After X-ray irradiation, ... Read More

A series of K(EuxCa1−x)PO4 (x = 0.001, 0.003, 0.01, and 0.03) phosphors were synthesized by the conventional solid-state reaction. To evaluate the phase purity of the as-prepared materials, X-r ... Read More

0.5, 1.0, 5.0, and 10.0 mol% Dy-doped 50NaPO3–50Al(PO3)3 glasses were synthesized by the melt-quenching method. All the samples had a high transmittance of up to 90% at visible wavelengths, and ... Read More

The optical, thermally stimulated luminescence (TSL), and optically stimulated luminescence (OSL) properties of CsBr:Cu transparent ceramics were evaluated. As the photoluminescence properties, t ... Read More

Undoped Lu2Si2O7 (LPS), Y2Si2O7 (YPS), and Gd2Si2O7 (GPS) single crystals are prepared by the floating-zone (FZ) method. The X-ray diffraction (XRD) patterns show the single phase of each materia ... Read More

Tb-doped GdTaO4 crystals were synthesized to investigate their photoluminescence and scintillation properties. Tb:GdTaO4 exhibits photo- and radioluminescence characterized by several sharp peaks ... Read More

We demonstrate the rapid synthesis of Ce3+-doped Lu3Al5O12 (Ce3+:LuAG) thick film phosphor grown by laser-assisted chemical vapor deposition. The radioluminescence properties of the film are comp ... Read More

We have studied the scintillation properties of non-doped and Pr-doped BaO–B2O3–SiO2 glasses and glass-ceramics. The glass transition temperature (Tg), the temperature of crystallization onse ... Read More

Toward developing super-broadband LEDs using NIR phosphors, the effect of Ca substitution on the luminescence of Cr-doped Y3Sc2Ga3O12 garnet (YSGG) was evaluated. The valence of chromium ions in ... Read More

Nd:SrY2O4 single crystals were successfully synthesized by the floating zone method, and their photoluminescence (PL) and scintillation properties were investigated. The X-ray diffraction pattern ... Read More

Nd-doped GdVO4 single crystals were synthesized and their photoluminescence and scintillation properties were evaluated. The Nd-doped samples showed scintillation due to the 4f–4f transitions o ... Read More

In this study, zirconium acetylacetonate (Zr(acac)4) containing the isotope 96Zr was studied as a liquid scintillator for the possible detection of neutrinoless double beta decay. To avoid the ab ... Read More
