Multipurpose Transparent Nanocomposites for Gamma Spectroscopy, Pulse Shape Discrimination, Thermal Neutron Detection, Radiation Shielding, and High Refractive Index Applications

Advanced Functional Materials, EarlyView.
Materials exist that are useful for gamma scintillation, radiation shielding, neutron‐gamma pulse shape discrimination (PSD), thermal neutron detection, or high refractive index applications. While certain materials have exhibited optimal performance for each of these applications, none achieve multiple functions.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Enhanced Scintillation with Uncorrelated TL and OSL Signals in LiCaAlF6:Eu Nanoparticles Enables Unprecedented Multimodal Radiation Dosimetry

Advanced Optical Materials, EarlyView.
The graphical abstract illustrates the coexistence of independent OSL and TL signals, demonstrating that the material preserves TL information even after complete OSL zeroing, enabling a dual dosimetric readout within the same material. Abstract The development of multimodal dosimeters capable of preserving independent luminescent signals is a ...
