Publikováno v: Journal of Sustainable Metallurgy. 7:519-536

The oxidation balance is arguably one of the most important parameters during pyrometallurgical processes. In many cases, iron is the most abundant multivalent element present in silicate slags. Within these molten oxide mixtures, the oxygen balance

“Glow-in-the-dark” materials are known to practically everyone who has ever traveled by airplane or cruise ship, since they are commonly used for self-lit emergency exit signs. The green afterglow, persistent luminescence (PeL), is obtained from

Achieving Efficient Red-Emitting Sr2Ca1−δLnδWO6:Mn4+ (Ln = La, Gd, Y, Lu, δ = 0.10) Phosphors with Extraordinary Luminescence Thermal Stability for Potential UV-LEDs Application via Facile Ion Substitution in Luminescence-Ignorable Sr2CaWO6:Mn4+

Autor: Henk Vrielinck, Dirk Poelman, Kai Li, Rik Van Deun, Jiaren Du, Dimitrije Mara

Publikováno v: ACS Materials Letters. 2:771-778

In this work, we adopt a facile rare earth ions Ln3+ (Ln = La, Gd, Y, Lu) substitution strategy to achieve the efficient red luminescence Sr2Ca1−δLnδWO6:Mn4+ (δ = 0.10), which extremely improves th...

Applied Spectroscopy (0003-7028) (SAGE Publications), 2022-02, Vol. 76, N. 2, P. 235-254

The chemical composition of recent and fossil organic-walled dinoflagellate cyst walls and its diversity is poorly understood and analyses on single microscopic specimens are rare. A series of infrared spectroscopic experiments resulted in the propos

Sputter deposition of copper oxide films

Autor: A. Dulmaa, Samira Khelifi, Diederik Depla, Henk Vrielinck

Publikováno v: Applied Surface Science. 492:711-717

Copper oxide thin films are grown by reactive magnetron sputter deposition. To define the parameter space to obtain CuO films, the influence of the oxygen partial pressure, the total pressure, and the discharge current was investigated on the phase f

Publikováno v: OPTICAL MATERIALS

The structural environment of the V-IV ions doped in the metal-organic framework (MOF) DUT-5(Al) (((AlOH)-O-III) BPDC) was studied with electron paramagnetic resonance (EPR). At low V concentrations, two different vanadyl components are observed in t
