“…Adding different ratios of europium (III) oxide or terbium (III) oxide to the base glasses produced six different activated scintillator samples, summarized in Table 3. Our previous studies showed that the 4% Eu concentration had greater relative luminosity than 5%, 6%, or 7% Eu concentration in similar high-density glasses [45]. The same was true for Tb.…”

“…We have previously developed several high-density scintillating glasses, specifically for proton radiography applications, activated with cerium, europium, and terbium, with densities ranging between 4.19 g/cm 3 and 5.84 g/cm 3 [45]. We determined that glasses activated with europium possessed favorable optical properties, such as transparency, and higher relative luminosity, making them especially promising for use in a proton radiography detector.…”

Proton radiography is a promising development in proton therapy, and researchers are currently exploring optimal detector materials to construct proton radiography detector arrays. High-density glass scintillators may improve integrating-mode proton radiography detectors by increasing spatial resolution and decreasing detector thickness. We evaluated several new scintillators, activated with europium or terbium, with proton response measurements and Monte Carlo simulations, characterizing relative luminosity, ionization quenching, and proton radiograph spatial resolution. We applied a correction based on Birks’s analytical model for ionization quenching. The data demonstrate increased relative luminosity with increased activation element concentration, and higher relative luminosity for samples activated with europium. An increased glass density enables more compact detector geometries and higher spatial resolution. These findings suggest that a tungsten and gadolinium oxide-based glass activated with 4% europium is an ideal scintillator for testing in a full-size proton radiography detector.

“…The scintillating glass with high potential can be used for radiation monitoring in high-energy physics, medical, industry, and security inspection. [1][2][3][4] Rare earth ions (RE 3+ ) doped glasses have been researched and developed for utilization in the screen/display, laser, LED, and also scintillator because they exhibit high luminescence efficiency under 4f-4f and 4f-5d transitions. [5][6][7] Especially, 4f-4f transitions have a sharp luminescence spectrum which is stable in different host materials.…”

The Dy3+:Na2O-Al2O3-Gd2O3-P2O5 (Dy:NAGP) glasses were fabricated to investigate the capability for radiation responses. The influence of Dy2O3 concentration on glasses properties were studied. The density and effective atomic number of glass increased with addition of Dy2O3 content. The glasses absorbed the photons in ultraviolet, visible light and near-infrared region. In photoluminescence (PL) spectra, the obvious yellow emission at 574 nm and blue emission at 482 nm of Dy3+ were both generated by the direct excitation and the Gd - Dy energy transfer. The PL decay time of glasses were in millisecond order. There was the thermal quenching observed in temperature dependent luminescence (TDL). The radioluminescence (RL) and protonluminescence (PrL) represented the emission pattern of Dy3+ similarly to PL spectra. The concentration quenching caused 0.50Dy:NAGP glass owning the highest PL and RL emission intensity. The X-ray imaging of developed glass using synchrotron light source was successfully imaged for the first time.

MnO2-lead materials have attracted attention in their applications as electrodes. This work reports a detailed spectroscopic study of the compositional variation of MnO2-xLead vitroceramic materials with varied Pb contents. The concentration variation of lead and manganese ions issystematically characterized throughthe analysis of X-ray diffraction (XRD), Fourier transform infrared (FTIR), ultraviolet–visible (UV–Vis), and electron paramagnetic resonance (EPR) spectroscopy.The MnO2-xLead samples consist of a vitroceramic structure with Pb, PbO, PbO2,and Mn3O4 crystalline phases. The introduction of higher Pb content in the host vitroceramic reveals the [PbO6]→[PbOn] conversion, where n = 3, 4, and the formation of distorted [MnO6] octahedral units. The UV–Vis data of the samples possess the intense bands between 300 and 500 nm, which are due to the presence of divalent lead ions (320 nm) and divalent and trivalent manganese ions (420 and 490 nm, respectively) in the structure of glass ceramics. The EPR data show resonance lines located around g ~ 8 and 4.3, and a sextet hyperfine structure at g ~ 2, which isascribed to the Mn+3 and Mn+2 ions.
