Elemental fluctuation in Gd3Al2Ga3O12:Ce crystals imposed by Li+ and Mg2+ codopoing: the impact on defects, luminescence and scintillation properties

The obtained measurements were attained in the course of executing a research endeavor that received financial backing from the National Science Centre, pursuant to the Sonata competition, under the registration identifier: 2020/39/D/ST3/02711. The data were accrued at the Department of Physics, Kazimierz Wielki University in Bydgoszcz. The investigations encompassed an in-depth scrutiny of luminescent materials manifested as composite single crystals of gadolinium-aluminum-gallium garnets. Meticulous analyses encompassing structural, luminescent, and scintillatory facets were conducted, encompassing a spectrum of temperatures ranging from low to elevated. Furthermore, a comprehensive evaluation of the prospective applications of said materials as scintillators was undertaken. The research focus pertained to composite aluminum-gallium garnets, doped with cerium, magnesium, and lithium ions.
