“…Anhydrous rare earth aluminium borates are an important class of materials which, in the last three decades, attracted large interest, due to the several applications within laser technology (Shumov et al, 1997;Dekker et al, 2001;Leonyuk et al, 2005). To date, they can be divided in two families.…”

Aluminium dimetaborates / Rare earth elements (REE) / Peprossiite-(Ce) / Single crystal structure analysis / X-ray diffraction Abstract. NonstoichiometricREEAl 2.07 (B 4 O 10 )O 0.60 (REE ¼ (La, Ce); Ce; Nd) dimetaborates have been crystallized and analyzed by means of single crystal X-ray diffraction. The compounds resulted to be isostructural within hexagonal space group P62m (n. 189), with the following unit cell parameters: (6) A; c ¼ 9.3170(10) A and V ¼ 170.44(4) A 3 (Ce); a ¼ 4.5830(7) A, c ¼ 9.2810(14) A and V ¼ 168.82(4) A 3 (Nd). The REE cations are surrounded by six oxygen atoms, making up a trigonal prismatic coordination; Al cation is surrounded by five oxygen atoms, resembling a square pyramidal coordination, while the BO 4 group displays tetrahedral arrangement. The three-dimensional framework can be described as a mica-like structure packed down crystallographic axis c, with layers of sixmembered rings of B tetrahedra alternated by inter-layers REE cations and layers of Al polyhedra. A complex network of REE . . . O and Al . . . O interactions concur to stabilize the framework.

“…Rare earth doped Ca 4 GdO(BO 3 ) 3 [7][8][9][10] compounds are important solid state laser materials. YAl 3 (BO 3 ) 4 doped with Nd 3+ [11], as well as, the 3d transition impurities [12,13] also find applications in solid state lasers. Li 2 B 4 O 7 can be useful for VUV laser [14].…”
