[17p-PA09-58] Development of Er-doped Mg4Ta2O9 Single Crystalline Scintillators
Keywords:scintillator, single crystal, near infrared emission
Near-infrared emitting scintillators have potential applications in high-dose field monitoring. In this study, Er-doped Mg4Ta2O9 single crystals emitting at wavelengths with good transmission efficiency in fibre optics were prepared and their photoluminescence and scintillation properties were investigated. In the X-ray-induced scintillation spectra in the near-infrared region,, peaks originating from Er3+ 4I13/2→4I15/2 transition were observed around 1000 nm and 1540 nm
