Synthesis and Characterization of a Compositionally Complex Aluminum Garnet Ceramic Scintillator: (Gd,Y,Tb,Lu) 3 Al 5 O 12 :Ce

Kaden Anderson, Nathan Gillespie, Luis Stand, Marlena Alexander et autres

ABSTRACT High‐energy X‐ray radiography plays a critical role in national security as it is used to scan cargo for illicit materials, including special nuclear materials. However, currently used scintillators face cost or performance drawbacks, driving the search for superior alternatives. We propose …

Composition Engineering and Crystal Growth of High-Entropy Rare-Earth Monoclinic Aluminates

Yauhen V. Tratsiak, Bethany Claes, Charles L. Melcher, Mariya Zhuravleva

We generated high-entropy (HE) compositions of rare-earth (RE) monoclinic aluminates using a combinatorial approach, grew crystals from the melt using the micropulling down method, and investigated phase formation, microstructure, and elemental segregation. All RE elements, except for Pm and Tm, were used …

Inside Front Cover: Stimuli‐responsive photoluminescent copper(I) halides for scintillation, anticounterfeiting, and light‐emitting diode applications

Dilruba A. Popy, Yashpal Singh, Yauhen V. Tratsiak, Abby M. Cardoza et autres

Near unity photoluminescence efficiency has been achieved in green emitting (TEP)2Cu2Br4 and orange emitting (TEP)2Cu4Br6. In both cases, emission originates from self-trapped excitons localized on the copper(I) halide structural units. The sensitivity of these compounds to the external stimuli coupled with their …
