Systematic synthesis and characterization of single-crystal lanthanide orthophosphate nanowires.
TL;DR: The obtained hexagonal structured lanthanide orthophosphate LnPO(4) (Ln = La --> Tb) can convert to the monoclinic monazite structured products, and their morphologies remained the same after calcination at 900 degrees C in air.

Lanthanide-doped nanoparticles with excellent luminescent properties in organic media
TL;DR: In this paper, surface-coated nanoparticles of LaF3 and LaPO4 doped with the luminescent trivalent lanthanide ions Eu3+, Nd3+, Er3+, Pr3+, Ho3+, and Yb3+ have been prepared.

Liquid-Phase Synthesis of Doped Nanoparticles: Colloids of Luminescing LaPO4:Eu and CePO4:Tb Particles with a Narrow Particle Size Distribution
TL;DR: In this paper, the authors used X-ray powder diffraction measurements and high-resolution transmission electron microscopy to confirm doping and energy transfer in LaPO4Eu and CePO4:Tb.

Sol–gel synthesis and photoluminescent properties of LaPO4:A (A = Eu3+, Ce3+, Tb3+) nanocrystalline thin films
TL;DR: In this article, a Pechini sol-gel process combined with soft lithography on silicon and silica glass substrates was used to fabricate rare earth ion (Eu3+, Tb3+, Ce3+)-doped LaPO4 nanocrystalline thin films.
Journal ArticleDOI
Synthesis of Eu3+-doped core and core/shell nanoparticles and direct spectroscopic identification of dopant sites at the surface and in the interior of the particles.
TL;DR: The core/shell synthesis investigated in this paper allows one to prepare doped nanoparticles that contain no other dopant sites than those known from the corresponding bulk material.

Optical Spectra, Energy Levels, and Crystal-Field Analysis of Tripositive Rare Earth Ions in Y2O3: I. Kramers Ions in C2 Sites
TL;DR: A survey of the literature reveals that there is still disagreement over the interpretation of the crystal-field splittings and subsequent wave functions of in both C2 and C3i sites as discussed by the authors.

Raman spectra of the rare earth orthophosphates
TL;DR: In this article, the Raman spectra of anhydrous crystalline samples of all of the lanthanide orthophosphates (with the exception of PmP04) have been obtained.

Ninefold coordination LaPO4: Pentagonal interpenetrating tetrahedral polyhedron
TL;DR: The crystal structure of LaPO4 has been determined from three-dimensional single-crystal X-ray diffraction data as mentioned in this paper, and the respective residual indices R1 and R2 have been refined to 0.020 and 0.021, based on 625 unique reflections.
