“…The other new peak at 470 cm À1 is assigned to Eu-O bond. 35 The above results indicate that the EuPO 4 are successfully coated on the SiO 2 submicro-spheres. Therefore, we suggest a possible formation mechanism of the core-shell SiO 2 @EuPO 4 nanostructures (Fig.…”

Cluster-like, flower-like and sphere-like EuPO 4 nano/microstructures and uniform core-shell SiO 2 @EuPO 4 nanostructures have been controllably synthesized by the hydrothermal route and co-precipitation method, respectively. The as-synthesized products are characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR). The possible formation mechanism of the as-synthesized products is proposed. The photoluminescence properties demonstrate that the locations of the strongest peaks of nano/microstructured EuPO 4 and core-shell

Europium-doped barium aluminate (BaAlxOy:Eu2+) phosphors were obtained at low temperatures (500°C) using the solution — combustion of corresponding metal nitrate-urea solution mixtures. The particle size and morphology and the structural and luminescent properties of the synthesized phosphors were examined by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), Electron diffraction spectroscopy (EDS) and photoluminescence (PL). It was found that the change in Ba: Al molar ratios showed greatly influence not only on the particle size and morphology, but also on their PL spectra and crystalline structure. The structure of BaAlxOy nanophosphors changes from a hexagonal Ba2Al10O17 phase for samples with 6:100 molar ratios to a hexagonal BaAl2O4 one with an increase in Ba content. The peak of the emission band occurs at a longer wavelength (around 615 nm) with a decrease in Ba concentration but displays a broad blue-green emission band composed from two emissions with the maximum at 495 and 530nm coming from Eu2+ in two sites for increasing Ba content. The blue-green emission is probably due to the influence of 5d electron states of Eu2+ in the crystal field because of atomic size variation causing crystal defects while the red emission is due to f - f transitions. These findings clearly demonstrate the possibility of fine tuning the colour emission.

“…Moreover, it is noted that annealing can cause an increase in the particle size [23] that does not permit one to unambiguously attribute measured properties to nanoscale crystals. According to a literature review, the hydrothermal method is preferable for the synthesis of lanthanide orthophosphates with lowdimensional particles (the particles for whose the size in one direction is sufficiently larger than in the remaining directions), because this method makes it possible to obtain the completely uniform particles size avoiding an additional high-temperature sintering and a multi-stage treatment.…”

The effect of hydrothermal synthetic conditions on the obtaining of lanthanide orthophosphates LnPO 4 (Ln = La, Pr, Nd, Sm) with different structure, size and shape of particles was revealed. The optimum conditions for preparation of anhydrous nanoscale lanthanide orthophosphates with monoclinic structure were determined. The prepared nanowhiskers had lengths ranging from 0.4 µm (for LaPO 4 ) to 5 µm (for SmPO 4 ), and the diameter -from 30 nm (for LaPO 4 ) to 200 nm (for SmPO 4 ). The size of particles synthesized under similar conditions increased with decreased of lanthanide ion radius.
