AB  - Dy3+-and Nd3+-doped YNbO4 powders were prepared using a mechanochemical method followed by annealing, and their photoluminescent properties were examined to assess the possibility of their use in phosphor thermometry. Luminescence intensity ratio technique was used as a temperature readout scheme for both YNba(4):Dy3+ and YNbO4:Nd3+ samples. The crystalline structure of the samples is confirmed by XRD measurements, while SEM was used for the microstructural and compositional characterization. Sample doped with Dy3+ ions emitting in the blue region has been investigated in the 293-773 K temperature range and exhibits maximal relative sensitivity of 1.97% K-1 at 300 K. YNbO4:Nd3+ sample showed intense NIR emission which fall into the first biological window. When heated from 303 up to 473 K relative temperature sensitivity of 0.28%K-1 at 300 K was achieved. Values of temperature sensitivities show that YNbO4 has a large potential for the development of thermographic phosphors in the blue and NIR spectral ranges when doped with trivalent Dy and Nd, respectively.

AB  - (Y1-xLnx)2O3 oxides (Ln = Y, Gd, Lu) doped with Eu3+ ions are widely used as commercialized scintillators in medical and industrial scanning applications, with high performance and attractive properties. In this work, effects of high-energy radiation on luminescence properties of (Y1-xGdx)2O3: Eu3+ powders with different particle sizes in the nanometric range are analyzed. Powders were prepared by polymer complex solution route, followed by annealing. Nanoparticles were obtained with an average size between 20 and 120 nm according to annealing conditions (time and temperature). Samples were exposed to gamma-irradiation (doses up to 4 MGy) on a commercial gamma-irradiation plant. The effect of irradiation on different nanoparticle size is followed by XRD, TEM and monitoring their luminescence properties. No change was observed in structure, morphology and steady-state emission. On the opposite after irradiation, excited-state lifetimes and quantum efficiency values are particle size dependent. © 2018 Elsevier B.V.
