Liming Zhang et al.
Journal of nanoscience and nanotechnology, 14(6), 4710-4713 (2014-04-18)
LiYbF4:Yb, Er nanoparticles have been successfully synthesized by thermal decomposition of multiple trifluoroacetic acid salts. The SEM and TEM results show the size of the LiYF4:Yb, Er nanoparticles is about 100 nm in diagonal line, and the morphology of the

Journal of nanoscience and nanotechnology, 14(6), 4313-4319 (2014-04-18)
Lutetium oxide nanocrystals codoped with Tm3+ and Yb3+ have been successfully synthesized via adjusting the pH values of the precursor solution in a hydrothermal method followed by a subsequent calcination process. The samples were systematically characterized by X-ray diffraction, field-emission
Thorben Rinkel et al.
Nanoscale, 6(23), 14523-14530 (2014-10-28)
We have studied the growth behaviour of sub-10 nm NaYF₄ upconversion nanocrystals of the hexagonal β-phase and the cubic α-phase. Ostwald-ripening of such particles in oleic acid/octadecene solvent results in broadening of the particle size distribution if the colloid contains

It is difficult to control the electrophoretic mobility in order to obtain high resolution among saccharides in complex samples. We report herein on a new affinity capillary electrophoresis (ACE) method for an anionic monosaccharide, N-acetylneuraminic acid (Neu5Ac), which is important

Pr3+/Yb3+ co-doped hexagonal NaYF4(beta-NaYF4) microprisms were synthesized by the hydrothermal method, and ethylenediaminetetraacetic acid (EDTA) was introduced to control the size of the microcrystal samples. Bright upconverted fluorescence emission was observed when the samples were excited with an infrared (IR)

Scientific reports, 5, 16761-16761 (2015-11-17)
The advent of flexible optoelectronic devices has accelerated the development of semiconducting polymeric materials. We seek to replace conventional expensive semiconducting photodetector materials with our cost-effective composite system. We demonstrate in this work the successful fabrication of a photoconductive composite

Carbohydrate polymers, 121, 302-308 (2015-02-11)
In this study, chitosan functionalized LaF3:Yb,Er upconverting nanotransducers (UCNTs) with controlled size and shape have been successfully synthesized by a facile one pot precipitation method. The chitosan encapsulated UCNTs show bright upconversion fluorescence upon excitation with 974 nm NIR region.

International journal of biological macromolecules, 72, 1308-1312 (2014-12-03)
In this work, we described one pot hydrothermal synthesis of surface modified water soluble YF3: Yb, Er upconverting nanofluorophores (UCNFs) using natural biopolymer chitosan. The obtained nanocrystals have undergone X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy
Ru Zhou et al.
Journal of nanoscience and nanotechnology, 14(6), 4196-4200 (2014-04-18)
The spectroscopic measurements of orthorhombic CaNb2O6 phosphor doped with Yb3+ ions have been performed. Low temperature spectra indicate that Yb3+ ions may occupy three types of nonequivalent sites inside the CaNb2O6 lattice: a main Yb3+ site dominating the near-infrared emission
Wanyue Shao et al.
Journal of nanoscience and nanotechnology, 14(5), 3887-3892 (2014-04-17)
Water-soluble BaYF5:Yb3+/Er3+ nanoparticles with the surface functionalized by a layer of poly(acrylic acid) (PAA) were synthesized via a facile one-step PAA-assisted hydrothermal method. Bovine serum albumin (BSA) protein was conjugated with BaYF5:Yb3+/Er3+ upconversion nanoparticles via free carboxylic acid groups on
