“…These decay times agreed with those previously reported. (32,(36)(37)(38) Figure 5 shows X-ray-induced scintillation spectra measured in the (a) UV-VIS and (b) NIR ranges. All the samples showed emission lines due to the 4f-4f transitions of RE ions.…”

Scintillators emitting near-infrared (NIR) photons have unique characteristics and have been attracting attention recently. For example, scintillators emitting NIR photons are expected to be effective tools for radiation dose monitoring in high-dose environments. In this study, YAlO 3 samples doped with various rare-earth ions (Er 3+ , Ho 3+ , Pr 3+ , and Tm 3+ ) were synthesized by the floating zone method and their scintillation properties from the UV to NIR range were evaluated. Regarding their scintillation detection property, the Er 3+ -doped sample indicated an approximately linear proportional relationship from 1 mGy to 10 Gy.

“…In the case of Eu 3+ , 5 major peaks can be detected in the emission spectra of SnO 2 :Eu 3+ when excited above the SnO 2 band gap: 5 D 0  7 F 0 (557 nm), 5 D 0  7 F 1 (593 nm), 5 D 0  7 F 2 (613 nm), 5 D 0  7 F 3 (650 nm), 5 D 0  7 F 4 (698 nm). Several other successful photoluminescence sensitization studies on Eu 3+ have been reported [3,6,10,11,[29][30][31][32][33][34][35][36][37][38][39][40][41]. Recent publications on Eu 3+ sensitization no longer focus on the novelty of emission efficiency but rather on the mechanisms of energy transfer -whether of resonance or non-resonance type [37] -and on the defect states in the nano lattice reportedly contributing to the overall efficiency.…”

Using a sol-gel synthesis method, nanoparticles of SnO 2 doped by a range of lanthanide ions (Ln 3+) were produced. The UV-visible photoluminescence (PL) emission and excitation spectra were analyzed. Upon excitation of the host oxide at energies above its fundamental bandgap, efficient sensitization of PL emission of all the lanthanide ions was observed. The effects of the Ln 3+ concentrations and ionic radii on the spectra were discussed and interpreted in terms of likely mechanisms of host-guest energy transfer.

“…Yttria ceramics have many potential applications such as lighting and display application [1,2], IR windows, laser host material [3,4], and high temperature resistant windows [5]. RE/Yb co-doped Y 2 O 3 transparent ceramics (RE = Er 3+ , Pr 3+ and Tm 3+ ), exhibited very e cient NIR-visible up conversion, therefore the optical properties of Y 2 O 3 ceramics doped with rare earth ions are of special interest for solid state lasers and scintillators [6][7][8][9]. Nowadays, Y 2 O 3 based ceramics are sintered by different methods such as hot pressing, conventional pressureless sintering, and spark plasma sintering [10][11][12][13][14].…”

Abstract Cerium doped yttrium oxide (Y 1.999 Ce 0.001 O 3 , Y 1.995 Ce 0.005 O 3, Y 1.99 Ce 0.01 O 3 ) nanoparticles have been synthesized by precipitation method with ammonium hydroxide as a precipitation agent. Partly agglomerated powders with the primary size of Y 2 O 3 nanoparticles with the mean size of ~ 55 nm and cubic crystal structure were prepared. The green compacts were prepared from alcoholic suspension with PEG as a dispersant by vacuum-pressure filtration. The green bodies reached relative density over 43 % while relative density of sintered specimens (1550 °C/3 h) were in all cases close to 98 %. All sintered ceria doped samples displayed dense microstructure with closed porosity and monomodal grain size distribution. The samples exhibit light emission in the blue wavelength range, centred at 430 nm.
