Miniaturization requests and progress in nanofabrication are prompting worldwide interest in
nanophosphors as white-emission mercury-free lighting sources. By comparison with their …

Abstract Nanocrystalline Ln3+‐doped YF3 phosphors have been synthesized via a facile
sonochemistry‐assisted hydrothermal route. YF3 nanoparticles are demonstrated to be a …

Y 2 SiO 5 is a very important material holding wide range of luminescent properties making it
a worthy luminous material. However, to extend its luminescent properties, doping can be …

The luminescence properties of colloidal YVO4: Eu nanoparticles (8 nm in diameter) are
investigated and compared to those of the bulk materials. The emission quantum yield of …

Pure hexagonal-phased Y1-x BO3: Eu x (x= 0− 0.30) nanocrystals with different particle
sizes were prepared by a facile sol− gel pyrolysis process, and their photoluminescence …

In order to improve the color purity of YBO 3: Eu, which is practically used as a plasma
phosphor, the lowering of the structural symmetry is proposed and subsequently realized in …

The use of near-infrared (NIR) ffuorescence is a promising approach for biomedical imaging
and detection.[1–6] Such applications with well performances require:(i) the excitation and …

To develop a good host material for red phosphors as well as a model for clarifying the
underlying correlation between structure and properties, tetragonal phased LaVO 4: Eu was …

Luminescent Ca1− xF2+ x: Eux nanoparticles were synthesized by a chemical co-
precipitation method in an ethanol solution. The Ca1− xF2+ x: Eux nanoparticles exhibit a …

Low-temperature phases of R2SiO5 (R= Y, Tb, Dy, Ho, Er, Tm, and Yb) were synthesized by
the sol-gel method. The X-ray powder diffraction patterns for these new phases were …
