“…A photoluminescence (PL) spectrometer was used to investigate the optical properties of the Gd 2 O 3 :Eu nanopowder according to the sensitizer concentration after exciting the phosphor using 214-nm ultraviolet rays that were produced using a xenon lamp. 4 The fabricated film had a thickness of 150 m. Line phantom images are acquired by using a coupled complementary-symmetry metal-oxide-semiconductor (CMOS) image sensor. Modulation transfer function (MTF) and detective quantum efficiency were used to evaluate the quality of the images.…”

Medical radiation imaging systems employ phosphors such as CaWO4 as X-ray receptor materials. Unfortunately, the conversion efficiencies of these materials are rather low (approx. 5%). Alternatives that comprise a bulk structure have been fabricated from rare earth metals, but they are not efficient enough to produce high quality images. Nano-phosphors do not suffer from the limitations inherent to the bulk structures of conventional phosphors. We examined the effects of sensitizer doping conditions on the optical characteristics and morphology of the rare earth phosphor Gd2O3:Eu to fabricate a novel type of nano-phosphor. We optimized a temperature solution-combustion procedure for producing phosphors doped with 5 wt% Eu. Scanning electron microscopy images showed that the phosphors were 20-30 nm in diameter and X-ray diffraction analysis revealed that they underwent polycrystalline growth upon the addition of a sensitizer, similar to the polycrystalline growth of bulk phosphors. In addition, the phosphors exhibited a strong peak at 613 nm and luminescence similar to conventional phosphors. Phosphors that were produced using citric acid as a sensitizer showed more than double the level of luminescence and could be used to produce higher quality images compared to non-sensitized phosphors. The phosphors also exhibited a high degree of luminescence stability.

“…[6][7][8] In order to avoid potential problems that could occur during synthesis in the solid phase, such as non-homogeneity, imprecise control of the cation stoichiometry and high processing temperature, it is more convenient to use wet chemical processes, such as hydrothermal synthesis, sol-gel, spray pyrolysis, co-precipitation, combustion synthesis, pulsed vapor deposition, etc. [9][10][11][12][13][14][15] In this study, the polymer complex solution (PCS) method, which is very simple, fast and cost-effective, was used. The PCS preparation procedure provides powders composed of well crystalline and uniform in size nanoparticles, which is a prerequisite for obtaining high-quality, transparent ceramics.…”

The samples, Lu2O3:Eu3+ (3at.% Eu) and Lu2O3:Sm3+ (1at.% Sm), were prepared via polymer complex solution method using polyethlylene-glyocol as the fuel and as nucleation agent for crystallization process. Knowing that lutetium oxide has high chemical stability and temperature resistance, in this paper we investigated possibility for its application in high-temperature phosphor thermometry. It is a non-contact technique that uses the thermal dependence of phosphor fluorescence to measure temperature remotely. The structural and morphological properties were performed through X-ray powder diffraction (XRPD) and transmission electron microscopy (TEM) investigations. The obtained results confirmed that this synthesis yields desired crystalline structure with particle size in the range from 30 to 50 nm. Photoluminescence emission measurements were recorded in the temperature range from room up to 873 K. The accomplished results demonstrate the performance of Eu3+ and Sm3+ doped Lu2O3 as high temperature thermographic phosphors of very good sensitivity.
