Developing halloysite-based X-ray scintillating nanocomposite enables red to green tunable emission behavior in epoxy resin
Source abstract
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@YF 3:Eu 3+ scintillator material that emits red light by utilizing halloysites (HALs) as base materials and then surface modified with europium-doped YF 3 via hydrothermal synthesis. The yielded product HALs@YF 3:Eu 3+ 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@YF 3:Eu 3+ 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.
