A time resolved microfocus XEOL facility at the Diamond Light Source

Journal of Physics: Conference Series, 2013
We have constructed a Time-Resolved X-ray Excited Optical Luminescence (TR-XEOL) detection system at the Microfocus Spectroscopy beamline I18 at the Diamond Light Source. Using the synchrotron in "hybrid bunch mode", the data collection is triggered by the RF clock, and we are able to record XEOL photons with a time resolution of 6.1 ps during the 230 ...

Microwave‐Facilitated Sensitization Route Boosting Efficiency, Thermostability, and Multifunction of Nanophosphors

Aggregate, Volume 6, Issue 10, October 2025.
A microwave‐facilitated sensitization engineering is proposed to construct new NSYP:Ce,Tb NPs with less oxygen vacancy, suppressing energy loss of Ce sensitizers and transferring more energy to Tb activators. As a result, the Ce sensitization for Tb achieves ultrahigh ET efficiency (92.6%), contributing to high IQE of 82.2%, along with outstanding ...

Geological sketch and the non-karstic caves of the Bakony Mountains in Hungary [PDF]

, 2013
[Abstract] The about 4000 km2 Bakony Mountains form the most extensive region of the Trans-Danubien Mountains between Lake Balaton and Marcal River. They have a typical medium relief, including plateaux of various heights, and denudated fault blocks ...

Sputter‐Grown MnBi2Te4 Thin Films: Magnetic Ground States and Phase Control

physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 10, October 2025.
Magnetron sputtering enables the growth of smooth MnBi2Te4 thin films with reduced twinning and improved crystallinity. Bibby et al. systematically correlate composition, structure, and magnetic properties, revealing that excess Mn destabilizes the target phase, while even stoichiometric films exhibit suppressed interlayer coupling and weak magnetic ...

β-Ga2O3:Cr nanowires with optical microcavities for determining local heating induced by x-ray nanobeams

APL Materials
This study explores the x-ray excited optical luminescence (XEOL) of optical microcavities fabricated in β-Ga2O3:Cr nanowires (NWs). XEOL measurements reveal prominent luminescence bands in the near ultraviolet-blue (NUV-B) and in the red-near infrared ...

New data on the lithostratigraphy of Beiras Group (Schist Greywacke Complex) in the region of Góis-Arganil-Pampilhosa da Serra (Central Portugal) [PDF]

, 2013
[Abstract] In the course of geological surveys conducted in the region of Góis (Central Portugal) a new unit was recognized at the top of Boque-Serpins Formation, characterized by the presence of levels of quartzites interlayered with shales, now called ...

Origin of the Surface Magnetic Dead Layer in Rare‐Earth Titanates

Advanced Materials Interfaces, Volume 11, Issue 35, December 12, 2024.
DyTiO3 perovskite titanates exhibit ferri‐magnetic ordering. Despite a nominal Ti valence of 3+, surface deviations to a more stable 4+ state disrupt this magnetic behavior for thin films. This valence evolution arises from short‐range ordered interstitial oxygen planes and Ti‐Dy cationic imbalance, inducing sufficient hole doping for a complete Ti4 ...

Luminescence of BaFBr and BaF₂ Crystals Irradiated by Swift Krypton Ions

Crystals
In this study, radiation damage in BaFBr and BaF2 crystals irradiated with 147 MeV 84Kr ions up to fluences of (1010–1014) ions/cm2 was investigated using X-ray excited optical luminescence (XEOL) and pulsed cathodoluminescence (PCL).

Photodynamic therapy for cancer: mechanisms, photosensitizers, nanocarriers, and clinical studies

MedComm, Volume 5, Issue 7, July 2024.
We highlight the development and molecular mechanisms underlying the activation of photosensitizers, the challenges of PDT in tumor management, and the advantages of nanocarriers‐based PDT against cancer. Abstract Photodynamic therapy (PDT) is a temporally and spatially precisely controllable, noninvasive, and potentially highly efficient method of ...
