The fundamental optical properties of dysprosium (Dy) doped strontium sulfide bulk samples for various dopant concentrations from 0.1 to 1.0 at.% were investigated by X-ray diffraction (XRD), electron paramagnetic resonance spectroscopy (EPR), room temperature photoluminescence (PL), photolumine...

Nowadays, permanent magnets (PMs) play a key role in electrical and electronic goods, and thus, their demand is incessantly increasing in countries such as Korea. These PMs significantly utilize dysprosium (Dy) and neodymium (Nd) during their manufacturing. But it is observed that when these mag...

The oxidation state studies of Mn1-xLnxS (Ln = Dy, Tm, Yb; x = 0; 0.01; 0.05) solid solutions was carried out for the first time using X-ray photoelectron and emission spectroscopy. The binding energy of the S(2p)-, Ln(4d)-, multiplet splitting analysis of Mn(3s)-level and the SKα1-line energy ...

The synthesis of the known pentamethylcyclopentadienylmolybdenum compounds [Mp*]2 (1, Mp*Cl (3), and Mp*H (7) (Mp* = Mo(η5-C5Me5)(CO)3) has been improved. The cyclic voltammetry of 1 shows a behaviour close to that of [Mp]2 (Mp = Mo(η5-C5H5)(CO)3) with a shift of potentials towards more negati...
