A Thermodynamic Study of Complex Formation between 15-Crown-5 with Mg2+, Ca2+, Sr2+ and Ba2+ in Acetonitrile Methanol Binary Mixtures Using Conductometric Method
The complexation reactions between Mg2+, Ca2+, Sr2+ and Ba2+ metal cations with 15-crown-5 (15C5) were studied in acetonitrile (AN)-methanol (MeOH) binary mixtures at different temperatures using conductometric method. 15C54 forms 1:1 complexes with Mg2+, Ca2+ and Sr2+ cations in solutions. The Ma2+ cati...
متن کاملSynthesis and luminescence properties of YF3:Ce3+/Tb3+ nanocrystals.
YF3:Ce3+, YF3:Tb3+, and YF3:Ce3+/Tb3+ nanocrystals were synthesized by an ethylenediaminetetraacetic acid (EDTA)-assisted hydrothermal method and characterized by X-ray diffraction and scanning electron microscope. In the excitation spectra, there is one broad excitation band at 285 nm for YF3:Ce3+ and 255 nm for YF3:Tb3+, which are related to the f-d excitations of the Ce3+ and Tb3+ in the hos...
متن کاملSynthesis and luminescent properties of Ln3+ (Eu3+, Sm3+, Dy3+)-doped lanthanum aluminum germanate LaAlGe2O7 phosphors
The novel phosphor of LaAlGe2O7 activated with the trivalent rare-earth Ln3+ (Ln = Eu, Sm, Dy) ions were synthesized by solid-state method, nd their characterization and luminescent properties were investigated. The absorption, emission and excitation spectra, and decay curves were mployed to study the luminescence properties. The calcined powders of the Eu3+, Sm3+ and Dy3+ ions doped in the La...
متن کاملOptical absorption and fluorescence properties of Dy3+: SFB glasses
This paper presents the preparation and spectroscopic characterization of Dydoped sodium fluoroborate (SFB) glasses of the type (50-x) B2O3 + 25 Na2O + 10 CaF2 + 10 AlF3 + 5 LaF3 + x DyF3 (x = 0.01, 0.1, 0.5,1.0, 2.0 and 4.0 mol%). By measuring the area under absorption bands, the experimental oscillator strengths are determined. The Judd-Ofelt (J-O) intensity parameters Ωλ (λ = 2, 4, 6) are ev...
