Mar 21, 2012 · In the present work, we report EPR investigations on Sn 1−x Mn x O 2 powders aimed to understand the origin of the observed signals due to the incorporated Mn ions and to establish the influence of the dopant concentration on the spectra.

Oct 4, 2016 · With the goal of optimizing the photorefractive response of the SPS crystals, we have initiated an experimental electron paramagnetic resonance (EPR) research program to identify and characterize all of the relevant electron and …

Aug 1, 2024 · Using EPR spectroscopy, Sn 3+ paramagnetic centres in two different crystallographic environments are identified, for the first time, in SrSnO 3 perovskites. These centres exhibit a remarkable stability at room temperature.

In as-grown crystals, the Sn vacancies are doubly ionized (V2−Sn) with no unpaired spins. They are then converted to a stable EPR-active state when an electron is removed (i.e., a hole is trapped) during an illumination below 100 K with 633 nm laser light.

Oct 2, 2024 · Sn(II) reactivity with molecular oxygen was evaluated through soluble oxygen and gas-phase O 2 consumption experiments. Electron paramagnetic resonance (EPR) was used to gain insight into the Sn(II) oxidation mechanism, identifying the presence of both ROS and reactive nitrogen species.

Oct 1, 2020 · The electron paramagnetic resonance (EPR) spectra were used to detect the presence of sulfur vacancies in samples of Vs-SnS 2 and Vs-SnS 2-O.

Feb 9, 2015 · Here we present the first report on Electron Paramagnetic Resonance operando spectroscopy and in situ imaging of a Li-ion battery using Li 2 Ru 0.75 Sn 0.25 O 3, a high-capacity (>270 mAh g...

Dec 13, 2024 · Our results show that the Te ions occupy Sn sites and S sites, where they serve as electron and hole traps, respectively. Electron paramagnetic resonance (EPR) spectra from five trapped holes and one trapped electron are observed at low temperatures after exposure to …

Feb 23, 2009 · This paper reports on the liquid-helium-temperature (5 K) electron paramagnetic resonance (EPR) spectra of Cr 3 + ions in the nanoparticles of SnO 2 synthesized at 600 ° C with concentrations of 0%, 0.1%, 0.5%, 1%, 1.5%, 2.0%, 2.5%, 3.0%, 5.0%, and 10%.

The by far strongest neighbour interaction with the rare isotope33S is detectable by electron paramagnetic resonance (EPR), while nine weaker cadmium interactions can be resolved with the electron nuclear double resonance (ENDOR) technique.
