Gadolinium orthophosphate weinschenkite type and phase change in rare earth orthophosphates

Synthesis and conductivity of GdPO4 nanorods: Impacts of particle size and Ca2+ doping

“…It means that the water content, n, for Gd 1−x Ca x PO 4 ·nH 2 O nanorods was 0.79 and 0.83 for x = 0 and 0.03, slightly smaller than that of 0.97 for x = 0.01 or 0.91 for x = 0.05. All these water contents were consistent to those previously reported for other nanoscale systems [33]. Fig.…”

Hydrothermal synthesis and photoluminescence of the monophosphate LaPO4:Eu(5%)

“…The chains are linked together by P-O-La bonds leaving an open channel along the hexagonal axis. The open channel has a minimum diameter of 3.4 Å and can contain 0-1 mol of water molecules [17]. The transmission IR spectrum is presented in the Fig.…”

Study of lanthanum orthophosphates polymorphism, in view of actinide conditioning

“…The chains are linked together by P-O-La bonds leaving an open channel along the hexagonal axis. The open channel has a minimum diameter of 0.34 nm and can contain from 0 to 1 mol of water molecules, according to the literature [17]. This water content was determined in the following from TGA experiment.…”
