“…The novel nanostructured NdF 3 glass-ceramic was obtained by Zhang et al upon heating of the precursor glass with the composition of 50SiO 2 -22Al 2 O 3 -10NdF 3 -18NaF (in mol%) as the bandpass color filter for wide-color-gamut white LED [30]. Another example of glass-ceramics obtained from the precursor silicate glass can be Tb 3+ -doped transparent oxyfluoride glass-ceramics containing LiYF 4 [31]. According to the authors, this material may be a novel scintillator applied for X-ray detection for the slow event [31].…”

The ErF3-doped oxyfluoride phospho-tellurite glasses in the (40-x) TeO2-10P2O5-45 (BaF2-ZnF2) -5Na2O-xErF3 system (where x = 0.25, 0.50, 0.75, 1.00, and 1.25 mol%) have been prepared by the conventional melt-quenching method. The effect of erbium trifluoride addition on thermal, structure, and spectroscopic properties of oxyfluoride phospho-tellurite precursor glass was studied by differential scanning calorimetry (DSC), Fourier-transform infrared (FTIR), and Raman spectroscopy as well as emission measurements, respectively. The DSC curves were used to investigate characteristic temperatures and thermal stability of the precursor glass doped with varying content of ErF3. FTIR and Raman spectra were introduced to characterize the evolution of structure and phonon energy of the glasses. It was found that the addition of ErF3 up to 1.25 mol% into the chemical composition of phospho-tellurite precursor glass enhanced 2.7 µm emission and upconversion. By controlled heat-treatment process of the host glass doped with the highest content of erbium trifluoride (1.25 mol%), transparent erbium-doped phospho-tellurite glass-ceramic (GC) was obtained. X-ray diffraction analysis confirmed the presence of BaF2 nanocrystals with the average 16 nm diameter in a glass matrix. Moreover, MIR, NIR, and UC emissions of the glass-ceramic were discussed in detail and compared to the spectroscopic properties of the glass doped with 1.25 mol% of ErF3 (the base glass).

“…Luminescent materials for radiation detection are roughly classified into two types: scintillators (1)(2)(3) and storage phosphors for dosimeters. (4 -7) Since the interaction probability of radiation species and elements varies widely, many kinds of materials including single crystals, (8 -31) glasses, (32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50) ceramics, (51)(52)(53)(54)(55)(56) and other materials (57)(58)(59)(60) have been researched. Requirements for properties vary considerably among applications, although high interaction probability, high luminescence intensity, and chemical stability are generally required.…”

We investigated scintillation decay times at different excitation γ-ray energies for commercial luminescent materials such as Ce:LaBr 3 , Eu:SrI 2 , Ce:LYSO [(Y,Lu) 2 SiO 5 ], and Ce:GAGG [Gd 3 (Al,Ga) 5 O 12 ]. Ce:LaBr 3 and Eu:SrI 2 did not show energy dependence, whereas Ce:LYSO and Ce:GAGG exhibited different decay curves at different excitation energies. In these materials, the energy dependence of decay correlated with the nonproportionality of scintillation light yield.
