“…The dominant absorption bands might be assigned to π-π* or n-π* transition of the 5-SSA ligand. It can be concluded that the red shifting of the absorption band in the UV-Vis spectra of Ho-MOF complex reminds the Holmium ion coordination with the 5-SSA ligand [28,41,42].…”

“…It has been overserved that there is a strong broad vibration peak which may be due to the ν(O-H) stretching vibration of the water molecules at 3353 cm -1 for the Ho-MOF complex [28,29,34,35]. The absence of strong vibration peak in the complex, while it has been observing in the 3067-1662 cm -1 region for 5-SSA organic ligand, can be interpreted as the depletion of the protons of the SO3H and COOH groups [28,29,34]. The strong vibration peaks are originated from carboxylate groups of νas(COO) at 1608 cm -1 and νs(COO) at 1506-1330 cm -1 region in the Ho-MOF complex.…”

“…Nowadays, hydrothermal technique is used extensively in the synthesis of the metal complexes, polymers and ceramics with increasing demands on the Nano-structures. Recent advances in Nano-technology have attracted considerable interest in the Holmium-based metalorganic frameworks (Ho-MOFs) which have interesting structural and luminescent properties [28,29]. Ho-MOFs which are frequently used in luminescent-based material designs is one of the prominent candidates in the development of the multifunctional materials.…”

In recent years, intensive studies have been made on metal-organic frameworks (MOFs) which is kind of spongy structures having excellent original architectures formed by ligands in organic forms and metal centers classified as binders. The main reason for this condensation is due to the great huge potential for such materials to be used in many technological application areas such as sensors, gas storage, photo-catalysis, organic light emitting diodes (OLEDs), solar cells (SCs) and luminescent emitting devices. The properties of the metal-organic frameworks depend on the selected organic ligands and metal ions. Therefore, new research and technology development (R-T-G) fields can be discovered with these materials that can be originally synthesized. In this work, Ho(III)-based metal-organic framework (Ho-MOF; [Ho(5-SSA)], 5-SSA = 5sulfosalicylic acid) was synthesized by hydrothermal method. The structural characterization has been made by powder Xray diffraction, a room temperature solid-state UV and FT-IR spectroscopy. In addition, the solid-state photoluminescence measurements have been taken at room temperature in the UV-visible and near-infrared region (NIR) and the energy transfer mechanism from 5-SSA ligand to the Ho +3 ion is investigated in detail. Under the excitation of UV light (at 349 nm), 5-SSA ligand exhibited a broad navy-blue emission while its Ho-MOF complex exhibited several characteristic emissions of the Ho +3 ion in the UV-Visible and NIR region. The excellent luminescent performances make this compound very good candidate for efficient luminescence materials.

“…7, H 2 L displays a broad yellow emission band at max = 592 nm, with CIE coordinates of 0.55 and 0.41, which can be attributed to ! * electronic transitions in the molecular orbital manifolds of the aromatic ring systems of the ligand, suggesting that there may be intraligand charge transfer (ILCT) (Coban et al, 2016(Coban et al, , 2018Oylumluoglu et al, 2017). The occurrence of a photo-induced electron transfer (PET) process may be responsible for quenching the luminescence of the ligand, depending on the presence of a lone pair of electrons on the N-and O-donor atoms in the ligand (Shafaatian et al, 2015;Basak et al, 2007).…”

The design and preparation of transition-metal complexes with Schiff base ligands are of interest due to their potential applications in the fields of molecular magnetism, nonlinear optics, dye-sensitized solar cells (DSSCs), sensing and photoluminescence. Luminescent metal complexes have been suggested as potential phosphors in electroluminescent devices. A new luminescent nickel(II) complex, [Ni(CHClNO)], has been synthesized and characterized by single-crystal X-ray diffraction and elemental analysis, UV-Vis, FT-IR, H NMR,C NMR and photoluminescence spectroscopies, and LC-MS/MS. Molecules of the complex in the crystals lie on special positions, on crystallographic binary rotation axes. The Ni atoms are six-coordinated by two phenolate O, two imine N and two hydroxy O atoms from two tridentate Schiff base 2,4-dichloro-6-[(2-hydroxypropyl)iminomethyl]phenolate ligands, forming an elongated octahedral geometry. Furthermore, the complex exhibits a strong green luminescence emission in the solid state at room temperature, as can be seen from the (CIE) chromaticity diagram, and hence the complex may be a promising green OLED (organic light-emitting diode) in the development of electroluminescent materials for flat-panel-display applications.

“…Nanoparticle modified nanofibers have been successfully applied in divergent areas such as catalysis [1][2][3], tissue engineering [4], photochemical applications [5][6][7], capacitors [8], energy applications [9], membrane electrodes in fuel cells [10], etc... Fuel cells (FC) are environmentally friendly alternative power sources [11] and until now from solid oxide to microbial FCs various studies have been reported which use the advantage of electrospun polymers [10,[12][13][14][15]. Electrospun polymers exhibit unique electrochemical activity.…”

Electrocatalytic effect of the untreated and TiO 2 +polyacrylonitrile (PAN) modified discarded battery coal (DBC) and pencil graphite electrodes (PGE) were evaluated in fuel cell (FC) applications. TiO 2 +PAN solution is coated on PGE and DBC electrodes by electrospinning. According to the FESEM and EDS characterizations, TiO 2 and PAN nanofibers are found to be approximately 40 and 240 nm sized. TiO 2 +PAN/PGE showed the best FC performances with 2.00 A cm-2 current density and 5.05 W cm-2 power density values, whereas TiO 2 +PAN/DBC showed 0.68 A cm-2 current density and 0.62 W cm-2 power density values. Electrochemical characterizations of PGE and TiO 2 +PAN/PGE electrodes were investigated by cyclic voltammetry and electrochemical impedance spectroscopy. Finally, long-term FC 2 measurement results of developed electrodes exhibited very reasonable recovery values. Along with the comparison of the electrode performances, the recovery of DBCs as electrodes for renewable energy production has been achieved.
