The U-value defined as the energy difference between the Eu<sup>4+/3+</sup> and Eu<sup>3+/2+</sup> charge transition levels (CTLs) is the most important parameter in constructing vacuum referred binding energy diagrams (VRBEs) with all the lanthanide CTLs with respect to the vacuum level of energy. The parameter is difficult to determine from...

Location of lanthanide levels in the bandgap, vacuum referred binding energy (VRBE) in the lanthanide ground state and energy of lanthanide charge transition levels (CTLs) are just three different namings for the same concept. A concept of importance for the performance of lanthanide activated compounds. Energy differences of CTLs with the...

Recent research activity on Sm<sup>2+</sup>-doped compounds has significantly increased the amount of available data on 4f<sup>5</sup>5d → 4f<sup>6</sup> decay times. This enabled the systematic comparison of spectroscopic and time resolved luminescence data to theoretical models describing the interplay between the 4f<sup>5</sup>5d and 4f...

Discovering energy storage materials with rationally controlled trapping and de-trapping of electrons and holes upon x-rays, UV-light, or mechanical force stimulation is challenging. Such materials enable promising applications in various fields, for instance in multimode anti-counterfeiting, x-ray imaging, and non-real-time force recording....

The luminescence properties of Tm2+-doped BaCl2 with an orthorhombic structure have been studied as a function of temperature and compared to other Tm2+-doped chlorides. In addition to the 2F5/2 → 2F7/2 (4f13 → 4f13) line emission, two 4f125d1 → 4f13 band emissions are observed at 20 K that can be ascribed to the spin-allowed (3H6,5d1)S=1/2 →...

Currently only Eu<sup>2+</sup>-based scintillators have approached the light yield needed to improve the 2% energy resolution at 662 keV of LaBr<sub>3</sub>:Ce<sup>3+</sup>,Sr<sup>2+</sup>. Their major limitation, however, is the significant self-absorption due to Eu<sup>2+</sup>. CsCu<sub>2</sub>I<sub>3</sub> is an interesting new small band...

Due to recent development in detector technology, photon-counting computed tomography (PCCT) has become a rapidly emerging medical imaging technology. Current PCCT systems rely on the direct conversion of X-ray photons into charge pulses, using CdTe, CZT, or Si semiconductor detectors. Indirect detection using ultrafast scintillators coupled...

Multimode luminescence relates to how charge carriers are transported and recombined in response to various physical excitations. It shows promising applications in many fields like advanced anti-counterfeiting, information storage and encryption. Enabling a stable single compound with multimode luminescence is a unique technology but still...

LaBr<sub>3</sub>:Ce<sup>3+</sup> is a compound with excellent scintillation properties, but its ultraviolet emission does not match well with the detection efficiency curves of silicon based photodetectors. In this work, Sm<sup>2+</sup> is studied as an activator for LaBr<sub>3</sub> as its near-infrared emission can be detected with close to...

Background: Mainly because of its long half-life and despite its scientific relevance, spectroscopic measurements of Lu176 forbidden β decays are very limited and lack formulation of shape factors. A direct precise measurement of its Q value is also presently unreported. In addition, the description of forbidden decays provides interesting...
