Synthesis and photoluminescence properties of erbium-doped BaF2 nanoparticles

Synthesis of BaF2:Ce nanophosphor and epoxy encapsulated transparent nanocomposite

“…1(a) shows the XRD pattern of a 1% Ce doped BaF 2 nanophosphor sample. The peak positions and intensities agreed well with the data reported for pure cubic BaF 2 crystals [17]. Broadening of the diffraction peaks was observed due to the nanoparticle size effect.…”

“…Synthesis of BaF 2 nanocrystal and Ce doped BaF 2 nanoparticles has been reported by various techniques such as hydrothermal reaction [11,12], liquid-solid-solution method [13], chemical precipitation [14,15], microemulsion [16,17] and thermal decomposition of barium trifluoroacetate [18]. For example, monodisperse oleic acid capped BaF 2 nanocrystals were synthesized by a liquid-solid-solution approach.…”

Solvothermal synthesis and characterization of Ln (Eu3+, Tb3+) doped hydroxyapatite

“…The superfluous HNO 3 was driven off until the Eu(NO 3 ) 3 crystal powders were obtained. The reverse microemulsion was prepared according to the literature [23]. In a typical process, 0.0141 g of as-prepared Eu(NO 3 ) 3 , 0.187 g of Ca(NO 3 ) 2 ·4H 2 O and 2 g of CTAB were dissolved in the mixed solvent containing 2 mL of H 2 O, 1.98 mL of n-butanol and 7.72 mL of n-octane (weight composition: CTAB/n-butanol/n-octane/H 2 O = 18.5/15.1/51.8/14.6).…”

Green Synthesis and Property Characterization of Single‐Crystalline Perovskite Fluoride Nanorods

“…Not surprisingly, fluorides as well as their doped analogues have found wide applicability as components of high-density optical devices, lenses, biological labels, sensors, and insulators. [18][19][20] What is less known is that ternary metal fluorides, possessing cubic perovskite structures with a chemical formula of AMnF 3 (A = K, NH 4 , Rb, Tl, Cs), are antiferromagnetic and that these materials have generated considerable interest due to their exceptional magnetic, piezoelectric, and photoluminescent properties. [21][22][23][24] In fact, this family of cubic perovskites provides an excellent example of simple cubic Heisenberg antiferromagnets with spin S = 5/2.…”
