Abstract

With the advancement of rare-earth luminescent materials, developing composites with tunable luminescent properties poses a significant challenge. In this study, we synthesized HALs@YF₃:Eu³⁺ scintillator material that emits red light by utilizing halloysites (HALs) as base materials and then surface modified with europium-doped YF₃ via hydrothermal synthesis. The yielded product HALs@YF₃:Eu³⁺ was characterized by TEM, SEM, XRD, and XPS, and then incorporated into the epoxy resin to endow X-ray scintillating abilities in the obtained composite with enhanced mechanical properties. Moreover, the green-emitting scintillator was also incorporated into the epoxy resin along with HALs@YF₃:Eu³⁺ with varying feed ratios to afford the epoxy resin composites with tunable emission behaviors from red to green. This study demonstrates a valuable approach for applying epoxy resin composite materials in the field of radioluminescence.

期刊介绍： Applied Clay Science aims to be an international journal attracting high quality scientific papers on clays and clay minerals, including research papers, reviews, and technical notes. The journal covers typical subjects of Fundamental and Applied Clay Science such as: • Synthesis and purification • Structural, crystallographic and mineralogical properties of clays and clay minerals • Thermal properties of clays and clay minerals • Physico-chemical properties including i) surface and interface properties; ii) thermodynamic properties; iii) mechanical properties • Interaction with water, with polar and apolar molecules • Colloidal properties and rheology • Adsorption, Intercalation, Ionic exchange • Genesis and deposits of clay minerals • Geology and geochemistry of clays • Modification of clays and clay minerals properties by thermal and physical treatments • Modification by chemical treatments with organic and inorganic molecules(organoclays, pillared clays) • Modification by biological microorganisms. etc...
