“…Eu(III) carboxylate dibenzoylmethanates (CDMs) have unique optical and magnetic properties [12,13]. In continuation of our studies [12][13][14][15][16][17] on investigation of the optical chemosensor properties of Eu(III) complexes, in the present work we report the results of an investigation of the luminescent chemosensor properties of Eu(III) CDMs of the composition Eu(Dbm) 2 Acid • nH 2 О, where Dbm is the dibenzoylmethanate ion; Acid is the anion of a carboxylic acid, namely, formic (Form − ), acetic (Ас − ), propionic…”

Luminescent chemosensor properties of Eu(III) carboxylate dibenzoylmethanates are observed. It is shown that the interaction of Eu(III) complexes with ammonia or methylamine vapors leads to an increase in the Eu(III) luminescence intensity. An optical response mechanism related to the interaction between the analyte and Eu(III) complex molecules and to suppression of luminescence quenching is proposed.

Luminescent europium-doped hydroxylapatite (EuXHAp) nanomaterials were successfully obtained by co-precipitation method at low temperature. The morphological, structural and optical properties were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier Transform Infrared (FT-IR), UV-Vis and photoluminescence (PL) spectroscopy. The cytotoxicity and biocompatibility of EuXHAp were also evaluated using MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide)) assay, oxidative stress assessment and fluorescent microscopy. The results reveal that the Eu3+ has successfully doped the hexagonal lattice of hydroxylapatite. By enhancing the optical features, these EuXHAp materials demonstrated superior efficiency to become fluorescent labelling materials for bioimaging applications.

“…In recent years lanthanide compounds are one of the research hotspots in material science and have gained more and more interest and, up to date, a large number of investigations have been carried out on the lanthanide compounds [1][2][3][4][5][6][7][8][9]. This is mainly because of the following reasons that lanthanide compounds show wide applications in many fields such as sensors, lightemitting materials, magnetic materials, cell imaging, electroluminescent devices, luminescence probes, catalysts and so forth [10][11][12][13][14][15][16][17][18][19]. The wide applications come from the various properties of the lanthanide compounds.…”

A new lanthanide compound [Gd(2,5-HPA)(2,5-PA)]n (1; 2,5-H2PA = 2,5-pyridinedicarboxylic acid) was obtained through hydrothermal reactions and structurally characterized by single-crystal X-ray diffraction. It possesses a three-dimensional (3-D) framework structure. Solid-state photoluminescence experiment revealed that it shows dark blue emission band, which can be assigned to the characteristic emission of the 4f electron intrashell transition of 6P7/2 → 8S7/2 (Gd3+). The energy transfer mechanism was explained by an energy level diagram of the gadolinium ion and 2,5-pyridinedicarboxylic acid ligand. It displayed remarkable CIE chromaticity coordinates of 0.1346 and 0.0678. The solid-state UV/Vis diffuse reflectance spectra unveiled that it possesses a wide optical band gap of 3.52 eV. Thermogravimetry (TG) measurements revealed that this compound is highly thermal stable up to around 500 °C. KEY WORDS: CIE, Energy transfer, Lanthanide, Photoluminescence, Thermal stability Bull.
