Synthesis, crystal structure and infrared study of LiEr(PO3)4

The crystal structure, thermal behaviour and ionic conductivity of a novel lithium gadolinium polyphosphate LiGd(PO3)4

“…It is to be noted that the adjacent polyhedra do not share any oxygen atoms among them. The shortest Gd-Gd distance 5.617(3) Å is an intermediate value of those in LiEr(PO 3 ) 4 (5.567(1) Å ) [24] and LiNd(PO 3 ) 4 (5.644 Å ) [7]. This fact is due to the difference of the ionic radii between the rare earth cations where r(Nd 3+ )4r(Gd 3+ )4r(Er 3+ ).…”

Flux-solvothermal preparation of dispersible LiLa0.4Nd0.6(PO3)4 microcrystals with regular morphology and superior fluorescence

“…One of the most important reasons is that the large size of the LNP crystal is too difficult to grow. In the past 40 years, two methods, including the high-temperature solution method [9][10][11] and ux method, [12][13][14] were used to grow LNP single crystals. Compared to the high-temperature solution method, the ux method has many outstanding advantages, such as wider applicability, simpler device, lower growing temperature and higher crystalline quality, so it has become the main method for preparing LNP crystal.…”
