Synchrotron radiation-based X-rays imaging by Dy3+ doped silicoborate glass scintillator: Fabrication, optical, luminescence and scintillation performances

Abstract

Dysprosium-doped glass scintillators have gained increasing attention due to their promising luminescent properties for applications in radiation detection, photonics, and optoelectronic devices. Glass matrices doped with Dy³⁺ ions exhibit strong emissions in the visible spectrum, particularly in the yellow region around 575 nm, making them suitable for scintillation application. These glasses are prepared via the melt-quenching technique at 1500 °C. The resulting materials are transparent and exhibit high densities, reaching up to 4.24 g/cm³. Absorption spectra reveal distinct bands that confirm the existence of Dy³⁺ ions into the glass matrix. Photoluminescence measurements indicate that the glass achieves maximum emission intensity at a Dy<inf>2</inf>O<inf>3</inf> concentration of 1.0 mol%, while X-ray induced luminescence peaks at 1.5 mol%. The measured decay time of the luminescence is observed within the millisecond range. X-ray imaging can be conducted at the Synchrotron Light Research Institute (Beamline 1.2W), providing high-resolution and precise analysis of scintillation performance. Dy³⁺-doped glass scintillators exhibit excellent optical properties and strong emission intensity, highlighting their potential as innovative materials for next-generation scintillation applications.
