Multimodal Imaging of Strain and Light Emission of Core–Shell InGaN/GaN Wires under a Sub‐Micrometer Polychromatic X‐Ray Probe

Advanced Materials Interfaces
We present a combination of µLaue X‐ray diffraction and X‐ray excited optical luminescence (XEOL) techniques to map local strain, orientation, and light emission in metalorganic vapor phase epitaxy (MOVPE) core–shell InGaN/GaN multiple quantum wells (MQW)

Toward Noninvasively Imaging pH at the Surface of Implanted Orthopedic Devices in Live Rabbits Using X-ray Excited Luminescence Chemical Imaging. [PDF]

Adv Healthc Mater
Imaging pH in a live rabbit at the surface of a sensor‐coated titanium plate using X‐ray excited luminescent chemical imaging (XELCI). A raster scanning X‐ray beam generates radioluminescence from a spot on the sensor, and the luminescence passes through the tissue and is collected at two wavelengths to determine local pH.

3D and Multimodal X-Ray Microscopy Reveals the Impact of Voids in CIGS Solar Cells. [PDF]

Adv Sci (Weinh)
3D X‐ray microscopy quantifies the distribution of voids in thin‐film solar cells and associated electrical performance deficits. Abstract Small voids in the absorber layer of thin‐film solar cells are generally suspected to impair photovoltaic performance.

Europium(III) diphenylphosphinate as a potential low-dimensional nanostructured coordination polymer scintillator

Materials Letters: X, 2023
Rare earth diphenylphosphinates – [RE(dpp)3]n – are low-dimensional nanostructured luminescent materials with considerable thermal and chemical stability, obtained in powder form, consisting of highly insoluble nanowire/nanorod-shaped particles.

A Scintillating One-Dimensional Coordination Polymer Based on Cadmium(II), N,N′-(1,4-Phenylenedicarbonyl)diglycinate, and 2,2′-Bipyridine: Crystal Structure, Hirshfeld Surface Analysis, and Luminescence Lifetime Properties ^†

Solids, 2021
In recent years, several coordination polymers of different dimensions and metal–organic frameworks were tested and expected to be good candidates for closing the gap between organic and plastic scintillators on the one hand side and inorganic ...

ZnGa2O4 : Cr3+@Calcium Phosphate Nanocomposite with Near‐Infrared Persistent Luminescence and High Stability

ChemPhotoChem, Volume 7, Issue 12, December 2023., 2023
Shine bright: Persistent luminescent Cr‐doped ZnGa2O4 (CZGO) is incorporated into an amorphous calcium phosphate (ACP) matrix. Annealing CZGO prior to ACP integration greatly improves its luminescence intensity and duration. Zn2+ redistribution from CZGO to ACP is identified, leading to the formation of Zn3(PO4)2 when immersed in water.

Bandwidth Control and Symmetry Breaking in a Mott‐Hubbard Correlated Metal

Advanced Functional Materials, Volume 33, Issue 41, October 9, 2023., 2023
The strength of the electron correlation is tuned by strain in a model system of SrVO3. Strain is shown to control the hopping between orbitals (bandwidth) and the orbital occupation. Tensile strain is shown to drive this metallic system toward a Mott insulating state.
