Potential laser gain media with the stoichiometric formula RETiNbO6

Synthesis, characterization and properties of [RE1−xREx′]TiNbO6 dielectric ceramics

“…Recently RETiNbO 6 (RE: rare earth ion) is reported as a useful ceramic material for dielectric resonator applications [10][11][12]. Single crystals of these groups of materials are recently reported as useful for miniature solid state and diode pumped lasers [13,14] The RETiNbO 6 compounds with atomic number of the rare earth ion in the range of 57-63 are known [13][14][15] to crystallize with orthorhombic aeschynite crystal structure with four formula units per unit cell and space group Pnma. Compounds with atomic number of the rare earth ion in the range of 64-71 have euxenite structure.…”

Synthesis and characterization of YNbTiO6:Dy3+ phosphor

“…Euxenite-type YNbTiO 6 is composed of distorted Nb(Ti)O 6 octahedral double layers joined together by edge and corner sharing and an YO 8 irregular polyhedron single layer which divides neighboring Nb(Ti)O 6 [17]. The XRD patterns of YNbTiO 6 and YNbTiO 6 :0.1Dy 3+ samples at different annealing temperatures are shown in Fig.…”

Synthesis and characterization of thermally stable, high Q, NdxY1−xTiTaO6 dielectric resonators

“…Sebastian et al [19] reported the possibility of using SmTiNbO 6 ceramics as good Dr. Surendran et al [20] reported that LnTiTaO 6 τ f . The principal difference between Ln 3+ in these structures is that in aeschynite orthorhombic structure they lie in closely connected chains where as in euxenite orthorhombic structures they lie on densely packed parallel planes [21]. Solomon et al [22] and Surendran et al [23,24] reported that by making a suitable solid solutions of both aeschynite and euxenite structures, it is possible to get compositions having low τ f and desirable microwave dielectric properties.…”
