A radioluminescent (RL) dosimetric system, based on a SiO2 optical fiber with the core doped by Ce3+ ions as luminescent activators has been investigated. Structural and properties of have studied Raman, refractive index, RL scintillation time decay measurements, compared to those obtained bulk material. The response composite made short portion active Ce-doped coupled long commercial one investigated x-ray irradiation. linear intensity found in dose rate interval 6×10−3–40mGy∕s together...
Nanoclusters of crystalline SnO2 have been grown in glass, starting from tin-doped silica prepared by a sol–gel method. Based upon particular choice molecular precursors, nanocrystallites with mean radius about 1 nm and quite narrow size dispersion were obtained, resulting wide-band-gap (>4 eV) quantum dots (QDs). In this system, differently other semiconductor-doped glasses, both the glassy host nanophase are oxides IV-group elements. Owing to their thermochemical compatibility, two...
Detectors are a key feature of the contemporary scientific approach to cultural heritage (CH), both for diagnostics and conservation. INFN-CHNet is network Italian National Institute Nuclear Physics that develops applies new instrumentation study CH. This process results in optimized traditional state-of-the-art highly innovative detection setups spectrometric techniques. Examples former X-rays, gamma-rays, visible-light particles spectrometers tailored CH applications, with performances,...
The RES-NOVA project is an experimental initiative aimed at detecting neutrinos from the next galactic supernova using PbWO$_{4}$ cryogenic detectors, operated low temperatures in a low-background environment. By utilizing archaeological lead (Pb) as target material, leverages its high radiopurity, large nuclear mass, and natural abundance of $^{207}$Pb, making it well-suited for exploring both spin-independent spin-dependent Dark Matter (DM) interactions via scattering. This work presents...
The glass-gem collection at the National Archeological Museum of Aquileia (Italy) was recently studied by in-depth archaeometric investigation campaigns, which are still running. Some objects in this very rich were characterized performing a completely non-destructive analysis. In order to enhance our knowledge Heritage Science, specific educational paths designed, which, one case, already tested summer school involving Italian middle-school students. This article will characterize single...
Stable white-emitting down-converted LEDs are straightforwardly prepared by bulk polymerization of an organic dye doped polymethyl-methacrylate (PMMA) shell directly on top a highly efficient commercial blue-emitting InGaN LED. Our optimized procedure allows for extending the form factor achievable luminescence converter (LUCO) material beyond conventional thin film and to produce devices with light bulb design. The selected dyes, Coumarin 30 red-emitting diketopyrrolopyrrole derivative,...
Abstract This work highlights recent application of energy-selective neutron imaging at the ISIS Neutron and Muon Source, specifically focusing on development Resonance Transmission Imaging (NRTI) INES instrument. NRTI is a nuclear technique based resonant absorption reaction, which combines sensitivity to elemental isotopic composition with detailed morphological information, using epithermal portion flux available instrument facility. Unlike standard radiography tomography methods,...
Excitation pattern and decay kinetics of ultraviolet photoluminescence porous silica are investigated between 4.5 10 eV by means synchrotron radiation. Spectra dominated a 3.7 emission similar to the recently observed oxidized Si nanostructures. Emission intensity is found be controlled material specific surface. Other emissions at 2.9, 3.8, 4.2 eV. All show lifetimes few nanoseconds. Spectral kinetic features sensibly different than in glassy SiO2, suggesting revision previous assignments
Neutron diffraction data with high real-space resolution are reported for an extensive series of cesium germanate glasses 2, 5, 10, 15, 18, 21, 25, and 30 mol % Cs(2)O, also pure GeO(2) in its vitreous, quartz, rutile forms.
