Eu- and Li-doped yttrium oxide nanocrystals [Y2-xO3; Eux, Liy], in which Eu and Li dopant ion concentrations were systematically varied, were developed and characterized (TEM, XRD, Raman spectroscopic, UV-excited lifetime, and ICP-AES data) in order to define the most emissive compositions under specific X-ray excitation conditions. These optimized [Y2-xO3; Eux, Liy] compositions display scinti...

We report on the development of scintillating bolometers based lithium molybdate crystals that contain molybdenum has depleted into double-? active isotope 100Mo (Li2100deplMoO4). used two Li2100deplMoO4 cubic samples, each which consisted 45-millimeter sides and had a mass 0.28 kg; these samples were produced following purification crystallization protocols developed for search experiments wit...

Because of broad interest in high-energy and nuclear physics community, mass production capacities of lead tungstate (PWO) crystals have been established. The optical and scintillation properties of PWO crystals, 20 each from two major vendors, were evaluated. The transmittance, emission and excitation spectrum, light output, decay kinetics and light response uniformity, as well as their degrad...

The energy resolution of the hadronic calorimeters is mostly limited by the fluctuation of the electromagnetic component in the development of the shower. The dual readout technique proposed by DREAM aims to correct event by event for this fluctuation measuring at the same time scintillation and Cherenkov light. In the last years the DREAM Collaboration has performed several tests to exploit th...

Current technologies for X-ray detection rely on scintillation from expensive inorganic crystals grown at high-temperature, which so far has hindered the development of large-area scintillator arrays. Thanks to the presence of heavy atoms, solution-grown hybrid lead halide perovskite single crystals exhibit short X-ray absorption length and excellent detection efficiency. Here we compare X-ray ...

In this paper the growth of a 16mm diameter Ce-doped Tl$_2$NaYCl$_6$ and its characterization as gamma-ray detector are reported. With 16 mm dia. x 8 cylindrical sample, energy resolution 4.1% (FWHM) at 662 keV light yield 27,800ph/MeV measured. Decay times 91 ns (34%), 462 (52%), 2.1 microseconds (15%) calculated. The x-ray excited emission spectrum exhibits bands that similar to other Tl-base...
