The temperature-dependent characteristics of fluorescence of several rare-earth-doped
ceramic phosphors has made these materials the focus of a major effort in the field of …

Orthophosphate compounds of the type A (PO4) include the minerals monazite [RE (PO4)
with RE= the light rare-earth ions, eg, La, Ce, Nd…], xenotime [Y (PO4), and also …

A simple hydrothermal method has been developed for the systematic synthesis of
lanthanide orthophosphate crystals with different crystalline phases and morphologies. It …

The enthalpies of formation for the compounds (RE3+) PO4,(where RE= Sc, Y, La–Nd, Sm–
Lu) were determined by oxide-melt solution calorimetry. Calorimetric measurements were …

The electronic structure of four ternary-metal oxides containing isolated vanadate ions is
studied. Zircon-type YVO 4, YbVO 4, LuVO 4, and NdVO 4 are investigated by high-pressure …

Under 980 nm excitation, strong upconversion emissions can be observed in Er 3+/Yb 3+-
codoped Y 2 O 3 nanoparticles at both high and low temperatures. The optical temperature …

In the context of phosphor thermometry, the most common measurement strategies, namely
the lifetime and the intensity ratio approach, have been compared. Using the phosphor …

Polarized Raman spectroscopy has been used to obtain the room-temperature phonon
spectra of the series of rare earth orthovanadate single crystals: Sm VO 4⁠, Ho VO 4⁠, Yb …

The effects of displacive, heavy-ion irradiation on the properties of synthetic single-crystals
of ZrSiO 4 (zircon), HfSiO 4 (hafnon), tetragonal ThSiO 4 (thorite), and monoclinic ThSiO 4 …

This paper presents the experimental investigations of steam flow with condensation in the
blading system of the low-pressure (LP) part of a 360 MW turbine. To this end, special …
