“…The mean Yb–O and Yb–N bond lengths of the complex 2 are 2.315 Å and 2.475 Å (Figure ), which are slightly shorter than the corresponding average distances of the complex 1. This can be explained by the fact that the radius of the Dy 3+ ion is larger than that of the Yb 3+ ion …”

Two novel complexes ([Ln(3, 3 (phen)] 2 (Ln = Dy(1), Yb(2); 3,5-Dipr-2-OHBA = 3,5-diisopropylsalicylic acid; phen = 1,10phenanthroline)) were synthesized and characterized by elemental analysis, conductivity measurements, IR spectra, single crystal X-ray diffraction, and thermogravimetric differential scanning calorimetry/Fourier transform infrared (TG/DSC-FTIR) technology. The fluorescent property of complex 1 was also studied. The two binuclear complexes are isostructural. Each Ln 3+ ion is octacoordinated, yielding a trigondodecahedron conformation. The thermal properties of the title complexes were investigated by simultaneous TG/DSC-FTIR techniques. The kinetic parameters of the first decomposition stage for the complexes were calculated by the integral isoconversional nonlinear method (NL-INT method), Starink method, Kissinger's method, and Ozawa−Doyle's method. The thermodynamic parameters (ΔH ≠ , ΔG ≠ , and ΔS ≠ ) at the peak temperatures of the DTG curves were also calculated. Heat capacities of the two complexes were measured by DSC. The values of the experimental heat capacities were fitted to a polynomial equation with the least-squares method. Besides, the smoothed heat capacities and thermodynamic functions (H T − H 298.15K ), (S T − S 298.15K ), and (G T − G 298.15K ) were calculated.

“…The second weight loss is 22.83 % from 400 to 500 ℃, which was due to the release of phen molecules. The IR spectra of the residue shows that the absorption band of C=N at 1625 cm -1 disappears [26]. Furthermore, it can also be concluded that the melting point of Eu(BPA) 3 phen is about 480 ℃.…”

The new color-tunable luminescent Eu/Tb(BPA)3phen composites have been successfully fabricated by the solvothermal reactions. The characterization of the final products have been investigated by field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), Thermogravimetric analysis (TG-DSC) and Ultraviolet and visible (UV-Vis) spectrophotometer. It is found that the geometry of the composite particles is regular by scanning electron microscopy image. Thermogravimetric analysis indicates that the initial decomposition temperature of the final products is 334 °C, approximately. The results demonstrate that Eu/Tb(BPA)3phen composites have excellent thermal stability. And the products after decomposition are stable oxides (Eu2O3 and Tb2O3). Furthermore, Eu and Tb ions complexes exhibit strong red and green luminescence, respectively. Emitting color of physically blended Eu(BPA)3phen and Tb(BPA)3phen composites can be tuned in a wide range from red to yellow to green under the excitation of 350 nm single-wavelength ultraviolet light. The CIE coordinates of CTb, C1, C2, C3, C4, C5, C6 and CEu are calculated as (0.24, 0.60), (0.31, 0.56), (0.33, 0.55), (0.38, 0.52), (0.40, 0.51), (0.43, 0.48), (0.54, 0.41) and (0.65, 0.34), respectively. The color-tunable luminescent materials can be widely applications in many fields, such as the optical and electronic devices, fluorescent probe and labels.

“…Besides, thermal analysis data is an important tool for estimating the thermal stability and shelf life of drugs. As one part of our continual effort in these complexes, herein a series of lanthanide complexes [Ln(3,4-DClBA) 3 phen] 2 (Ln = Ho(1), Nd(2), Sm(3), Dy(4), Eu(5), Tb (6), Yb (7) and Er (8),3,4-DClBA = 3,4-dichlorobenzoate, phen = 1, 10-phenanthroline) were synthesized and characterized by elemental analyses, molar conductance, IR and UV spectra, TG/ DSC-FTIR technique, and X-ray crystallographically. The thermal decomposition processes are studied using the TG/DSC-FTIR coupling techniques.…”
